Amazon Web Services (AWS) Cloud Support Engineer Interview Guide

Typically, the interview process for the AWS Cloud Support Engineer consists of 2 rounds as under:

  • Phone Screen
  • Onsite Round 

Phone Screen


The recruiter screen is a 30-minute interview with the hiring manager. This is a get-to-know-you interview where the interviewer assesses your cultural and experiential fit for the role & company. Most of the questions will be based on your previous experience/resume. So, be very familiar with everything in your resume. Remember to keep answers short & structured. You can also expect a few basic questions on topics such as OS and Networking. Also, keep a short and crisp answer ready for common questions such as "Why do you want to be a cloud support engineer?" or "Why Amazon?"


  • Revise and re-revise everything you have mentioned in your CV.
  • Prepare answers to questions involving your motivation for the role and company.

Onsite Round


Once you clear the phone screen, you will be called for the onsite round. The onsite round for the AWS Cloud Support Engineer consists of 4 rounds, 3 of which will be technical rounds and the last one will be an HR round each. Each of these interviews is going to be one hour long.

  • Operating System (OS) & Networking 
  • Database Management System (DBMS)
  • Data Structures
  • HR round

Let's look at each of these rounds in a little more detail.

Operating System (OS) & Networking Interview

OS questions will focus on OOPS, fundamentals of Operating systems. Topics like sockets, memory models and threads are very likely to be asked. Networking questions will focus on network architecture, lan, routers and so on. Also, expect questions on cloud computing since this will be the more focus of the role.

Database Management System (DBMS)

In database management, questions on data abstraction and data independence, database objects, multimedia database interfaces, categories of end-users, and use of DBMS in system software are commonly asked.

Data Structures

Data Structures questions will check the clarity of your concepts. Questions will involve writing functions to implement various operations on data structures. Expect a good number of questions on arrays, stacks, and linked lists. Be prepared to write algorithms involving these data structure types.

HR Round

The HR interview is a non-technical round. It is conducted by a senior HR manager from the company. Questions will be almost exclusively based on your CV and previous work experience, quite similar to the Phone Screen. There may also be some situation-based questions to gauge your motivation for the role and company.

There will also be situational questions to assess your leadership skills and behavioural aspects of your personality.

A major focus in the HR interview will be Amazon's 14 Leadership Principles. All situational questions will necessarily involve these principles. So, try to use them whenever you can in your answers.
