On 24 August 2026 I opened three job adverts that carried the same two-word title: cloud engineer. One wanted a .NET and React developer. One wanted someone who could schedule GPU clusters. One wanted an active US Secret security clearance. Nothing in the three overlapped except the title.
That is the problem with almost every guide to cloud engineer interview questions. It answers a question that has no single answer, and it answers it without ever looking at a real job advert or a real candidate.
This article does the opposite. Everything below is an exhibit: a live requisition, a dated candidate report, or a search that came back empty.
Where I could not establish something about cloud engineer interview questions, the article says so instead of filling the gap.
Exhibit One: Why Cloud Engineer Interview Questions Have No Single Answer
Three adverts, one title. All three were fetched and confirmed live while researching this article.
Optum — “Azure Cloud Engineer”, Basking Ridge, New Jersey
Required: “2+ years of professional software development experience”, “2+ years of experience developing Web APIs using .NET”, “2+ years of experience building modern front-end user interfaces with React”, and “2+ years of experience writing and optimizing complex SQL Server queries.”
Terraform is mentioned zero times. Python, zero times. PowerShell, zero times. AZ-104, zero times. This is an application developer job wearing a cloud job title.
Google — “Strategic Cloud Engineer, Platform and AI Infrastructure”, Sydney and Docklands, Australia
Minimum qualifications include “Experience coding in one or more general purpose languages (e.g., Python, Java, Go, C or C++) including data structures, algorithms, and software design” alongside six years of infrastructure automation and experience in “networking, AI Infrastructure (TPU, GPU, NPUs etc), compute infrastructure.”
Preferred qualifications ask for “Experience in large-scale GPU cluster resource elastic scheduling, cloud rendering, and AI container inference management.”
True Anomaly — “Staff Mission Cloud Engineer”, Denver, Colorado
Requires “10+ years of hands-on experience in cloud engineering or infrastructure, with significant experience architecting and operating AWS and Azure environments at scale”, plus a “DoD 8140 IAT Level III certification (CASP+, CISSP, CISA, or equivalent)”, an active Secret clearance, and US citizenship under ITAR.
Three live adverts. Three interviews with nothing in common. A candidate who prepared for any one of them using a generic list of cloud engineer interview questions would walk into the other two unprepared.
That is the first thing to understand about cloud engineer interview questions: the title is a hiring convention, not a job description, and the interview follows the job rather than the title.
Exhibit Two: The Claim Nobody Could Show Me
The most specific competitor page on this topic is a recruiter-authored guide published 28 April 2026 and updated 29 July 2026. It describes a six-stage loop with a sixty-minute infrastructure-as-code technical screen featuring live coding in Terraform or Pulumi, and states: “Most companies now do this as a live session, not a verbal quiz.”
That sentence would change how you prepare, and it is the only claim in the whole genre of cloud engineer interview questions guides that would. So I went looking for one candidate — anywhere — who had sat one.
Six differently-phrased searches for first-hand accounts of a live Terraform or infrastructure-as-code exercise returned overwhelmingly listicles and vendor blogs.
I found exactly two things that were not: a Glassdoor interview-question entry for a Proofpoint Senior DevOps Engineer role reading “Pair Programming to debug Terraform code” — undated, with no narrative attached — and a publicly published pair-programming exercise from the consultancy Able that asks candidates to deploy a stack using “terraform, cloudformation, pulumi, ansible, etc.”
So the format exists. What does not exist, as far as I can find, is evidence that it is what most companies do, or that it belongs in a general account of cloud engineer interview questions. Two artefacts, one of them a single undated line, and neither describing writing Terraform from scratch against a timer, is not a standard.
I am not saying it never happens. I am saying that a claim presented as the current standard has, as far as I can find, very little public first-hand evidence behind it.
The guide does state a provenance. It says its questions “come from live cloud engineering interview loops at companies in SaaS, fintech, healthcare IT, and mid-market enterprise, not from other lists.” But it names no company, no date and no candidate, so there is nothing a reader can check.
What is verifiable: Terraform appears in 27.62% of UK cloud engineer job adverts, according to ITJobsWatch data covering the six months to 23 August 2026. Learning Terraform is clearly worth your time. Being told with confidence that you will be made to write it live, under a timer, is a different claim — and it is the thinly supported one.

Exhibit Three: What Candidates Were Actually Asked, With Dates
Here is where the standard cloud engineer interview questions article quietly falls apart.
Almost every one of them opens with definitional questions: what is cloud computing, what is the difference between IaaS and PaaS, what is virtualization.
I ran two searches looking for any candidate who reported being asked those questions in a real interview. Both came back with question banks, course pages and listicles — and zero candidate reports.
Meanwhile the actual candidate reports on Glassdoor’s generic cloud engineer page contain no definitional questions at all. They contain these, quoted verbatim with the dates the reviews carry:
- “Asked me about Networking, Windows Servers, SQL query and Linux. Basic commands and scenario based question.” — Amazon, Cloud Support Engineer, 29 October 2015
- “Explain what happens when you open a web browser and type in ‘google.com'” — Amazon, Cloud Support Engineer Graduate, 3 October 2015
- “You need to patch openssl. What is the quickest way or efficient way of installing the package?” — Amazon, Cloud Support Engineer Linux, 14 November 2017
- “Why ping is important when troubleshooting ‘Unable to take RDP’?” — Amazon, Cloud Support Engineer, 14 February 2018
- “What is fstab?” — Amazon, Linux – Cloud Support Engineer, 15 August 2019
- “how will you T-shoot if you cant connect to xyz.com?” — Amazon, Cloud Support Associate, 28 March 2020
Look at those dates. All ten candidate reports on that page were filed between 2015 and 2021. Every guide recycling them carries 2026 in its title.
The year is on the headline, not on the questions.
Genuinely recent reports do exist on Amazon’s Cloud Support Engineer page, and they say something consistent with each other and with almost nothing in the listicles.
An accepted-offer report from Auckland, New Zealand dated 13 August 2026 describes “1 Phone interview talking about mostly Stuff on my CV. Then 1 Technical interview, then 2 behavioral interviews with two different managers”, with the technical content being “What is the DNS flow. Stuff about linux commands such as what does Chmod do etc…”
A report from Herndon, Virginia dated 20 June 2026 describes “a 4 round loop. The first two rounds focused on networking and troubleshooting, plus questions about your domain. The last two rounds are just answering questions using leadership principles in STAR format”, and gives a sample behavioural prompt: “Tell me about a time you automated something.”
DNS, Linux commands, troubleshooting, STAR stories. No algorithms. That is what current cloud engineer interview questions look like at the one employer with enough recent reports to see a pattern.
The Coding Round in Cloud Engineer Interview Questions: A Three-Way Split
This is the question that should organise your preparation, and it is the one almost no guide addresses. The honest answer is that it depends on which of the three cloud engineer jobs you are actually interviewing for.
Big-tech infrastructure roles: yes, and it is easier than you fear
Candidate discussion on Blind is consistent that large tech employers run algorithm rounds for infrastructure and DevOps roles.
One thread on whether DevOps engineers face LeetCode-style interviews has a commenter answering “depends on the company but in big tech (google, meta, etc) yes”, and a second adding “Even Bloomberg does Leetcode for Devops”. Neither comment carries a visible date or employer tag.
An Apple SRE thread, which carries no visible date and should be treated cautiously, has two separate replies converging on “Leetcode easy/medium”, with one adding “maybe a Linux/bash grilling in a follow up interview.”
Easy to medium, consistently. Nobody in these accounts reports hard algorithm problems. And the coding round sits alongside Linux and systems questions rather than replacing them.
Google’s advert does not leave this to inference either: its minimum qualifications name “data structures, algorithms, and software design” in the same breath as the coding requirement. At this end of the market the algorithm round is written into the requisition.
Cloud support roles: no algorithm round at all
This is the best-evidenced finding in the research, and it is the part of cloud engineer interview questions that the listicles most reliably get wrong.
Across Glassdoor’s Amazon Cloud Support Engineer page, a separate Cloud Support Engineer II page with reports from Dublin, London and Nairobi, and two Blind threads including one posted around 16 August 2026, no candidate in a US, UK or Irish location describes an algorithm round.
What they describe instead: networking and Linux troubleshooting, domain-specific depth in whichever service area the team supports, and Leadership Principles answered in STAR format. Advice on the August 2026 Blind thread was “Find out what services the support team you’re applying to handles, and then prepare for those specific topics and concepts.”
One prep vendor lists data-structures problems for this loop. It cites no sources and shows no publication date.
An India-based Glassdoor page mentions an “Online round checking basic and coding” — that is India-specific evidence and may reflect a campus screening stage that does not appear in Tier 1 hiring. A published Indian candidate account from November 2023 reports four rounds with no coding component at all.
Those two sources contradict each other. I am not going to resolve them for you, and any page that presents Indian campus-screening evidence as a description of US or UK cloud engineer interview questions is quietly resolving it for you without saying so.
Enterprise IT roles: whatever the underlying stack is
Optum’s Azure Cloud Engineer advert is the case in point. That interview will be .NET, React and SQL Server, because that is what the job is. No amount of studying cloud engineer interview questions would have told you that.
And the honest gap in the evidence
For the mid-market cloud engineer job — not a hyperscaler, not cloud support, not a disguised app-dev role — which is where a great many readers are actually applying, I could not find a single first-hand account describing what the technical round contained. That is a real limitation of this article, and I would rather state it than invent a loop diagram.
Cloud Engineer Interview Questions About Certifications
The pattern in the evidence is that certifications move you past screening and do very little inside the room.
A Blind thread on AWS certification value has three commenters agreeing on roughly that. Verbatim: “Certifications aren’t important. What is important are accomplishments you can highlight on your resume that demonstrate the associated skills.”
A longer reply about the professional-level architect certification says it “will help you get through HR and SEO but a good interviewer won’t care one way or the other”, and that it demonstrates “you know how to design systems in AWS at a lucidchart level but not necessarily how to implement them.”
The same commenter does cite a roughly $20,000 pay differential in roles where being a cloud architect matters.
An honesty note on this one: the thread carries no visible date, and it would not load when I went back to re-check it before publishing. These quotes are reported from the original reading rather than independently re-verified, and should be weighted accordingly.
The advert data points the same way. ITJobsWatch records the AWS Certified Solutions Architect certification in 152 UK permanent vacancies over the six months to 23 August 2026 — described on that page as 0.14% of all permanent UK jobs.
Over a comparable window, cloud-engineer-titled roles ran to 1,267 permanent vacancies. The certification most heavily marketed to cloud engineers is named in a small minority of the adverts.
The exception is worth knowing: True Anomaly’s advert genuinely requires a certification. It is DoD 8140 IAT Level III, a compliance credential, not a cloud vendor badge.
What the Market Numbers Say
Pay and demand shape which cloud engineer interview questions you should bother preparing for, so the numbers are worth a section. All figures below recompute as new adverts are indexed, so they are stamped with the window they were read in.
ITJobsWatch, six months to 23 August 2026: UK cloud engineer median salary £70,000, from 964 salaries quoted across 1,267 permanent vacancies, up 3.70% year on year. The contract page, same window, shows a £525 median day rate across 751 contract vacancies, up 5.00%.
These numbers move. When I first read those two pages they showed different window end-dates and slightly different vacancy counts; a day later they had converged. That is normal for a rolling index, and it is why single-figure salary claims in interview guides age badly.
The same source shows the adjacent titles diverging. Cloud architect: £90,000 median across 347 vacancies, with “Security Cleared” appearing in 24.50% of them and Terraform in only 9.51% — measurably less hands-on than the engineer role. FinOps: £85,000 across 214 vacancies, up from 44 vacancies a year earlier.
For US context, be careful with what gets quoted. The Bureau of Labor Statistics has no cloud engineer occupation at all.
Its nearest proxy, network and computer systems administrators, reported a median wage of $96,800 in May 2024 and is projected to decline 4 percent from 2024 to 2034. That is the sysadmin job shrinking, not the cloud job.
Glassdoor’s US cloud engineer average of $151,879 is worth knowing, but that page states it was last updated 10 April 2025, so treat it as a 2025 figure.
A Small Warning About Job Adverts
A last practical note, because it affects how you use any guide to cloud engineer interview questions, including this one. Nine postings went into the research for this article. Six of them were already dead when I checked — and the three quoted at the top were live at the time of writing, which is exactly the point. Freshness is a property of the day you look.
Two Amazon requisitions returned 404s. A Google Cloud Engineer I posting returned “Job not found. This job may have been taken down.” A Wise London role had expired.
A Northwestern Mutual posting showed “Sorry, this job was removed at 12:38 p.m. (UTC) on Tuesday, Aug 11, 2026” — while the same job board’s search listed it as reposted eight hours earlier.
Freshness signals on job boards are not reliable. Check the employer’s own careers page before you invest preparation time in a specific requisition — and be sceptical of any guide to cloud engineer interview questions that quotes a job advert without a date.
How To Prepare, Given All That
The preparation follows from the diagnosis rather than from a question list. Nothing below is a list of cloud engineer interview questions to memorise, because the evidence does not support one.
Read the advert as the syllabus. The three exhibits above should have retired any belief that the title tells you what to study. Whatever the required-qualifications section names is what the technical round will cover — and it beats any general list of cloud engineer interview questions.
Get genuinely fluent in Linux and networking. Every dated candidate report in this article, from 2015 through to August 2026, involves troubleshooting, Linux commands, DNS and TCP. It is the single most durable element in the evidence.
Prepare algorithm practice only if you are interviewing at a large tech employer, and cap it at easy-to-medium. The candidate accounts do not support grinding hard problems for these roles.
Write STAR stories if a support role or an Amazon team is involved. Behavioural rounds are half the AWS Cloud Support loop by every account of it.
Learn Terraform because a quarter of UK adverts ask for it, not because someone told you there is a live exercise. Be ready to discuss infrastructure-as-code work you have genuinely done.
If you are weighing this role against adjacent ones, the same “does this interview even have a coding round” test applies to a title with the identical ambiguity problem — see our guide to systems engineer interview questions, and the wider index of interview questions by role.
Cloud Engineer Interview Questions: FAQ
Do cloud engineer interview questions include LeetCode problems?
At large technology employers, candidate accounts consistently say yes: cloud engineer interview questions there include algorithm problems at easy-to-medium difficulty, alongside Linux and systems questions. At cloud support roles such as AWS Cloud Support Engineer, no candidate report in a US, UK or Irish location describes an algorithm round. For mid-market employers, there is no public first-hand evidence either way that I could find.
Will I have to write Terraform live in the interview?
One widely-read recruiter guide asserts this is now standard. Six searches for first-hand candidate accounts turned up two items: an undated Glassdoor entry for a Proofpoint DevOps role describing “Pair Programming to debug Terraform code”, and a published pair-programming exercise offering Terraform as one option. The format is real but thinly evidenced, and nothing I found supports “most companies”. Terraform is genuinely in 27.62% of UK adverts for the role, so learn it.
Are definitional cloud engineer interview questions like “IaaS vs PaaS” actually asked?
Almost every guide opens with them. I found no candidate report of anyone being asked one. The real reports are about fstab, ping, openssl patching and what happens when you type a URL into a browser.
Does an AWS certification get me the job?
Candidate opinion on Blind is that certifications help you clear recruiter screening and carry little weight with the interviewer. The AWS Solutions Architect certification is named in 152 UK permanent vacancies in the six months to 23 August 2026, against 1,267 cloud-engineer-titled vacancies — so most adverts do not ask for it.
How do AWS cloud engineer interview questions differ for support roles?
Candidate reports describe technical rounds on networking, Linux and the specific services the team supports, followed by Leadership Principles rounds in STAR format. Accounts disagree on the round count — Glassdoor’s aggregate says four, a Blind commenter describes six stages, a prep vendor says two. AWS itself publishes no description of the loop that I could find.
Is the cloud engineer job market growing?
In the UK, the advert data says yes: 1,267 permanent vacancies and a £70,000 median in the six months to 23 August 2026, up 3.70% year on year, with contract rates up 5.00%. US data is harder to read because no official occupation matches the title.
The Short Version
Cloud engineer interview questions cannot be answered as a list, because the title covers at least three unrelated jobs with three unrelated interviews. The coding round exists at hyperscalers and does not exist in cloud support. The definitional questions that open every guide have no candidate evidence behind them. The live Terraform exercise that the most confident guide promises has almost none behind it either.
The advert in front of you is a better study guide than any list of cloud engineer interview questions, this one included. Read it as the syllabus, and get good at Linux.
