(majority of questions were on Networking, Database, OS, AWS services.)

The First Round of the process is the online round which consists of 4 subparts. Duration was 90 mins.

1^st subpart – Real-Time Implementation of Work Environment where graphs regarding server details and other information are provided and the candidate is given a workflow based on which the candidate must take further decisions on how to troubleshoot the assigned problem, questions regarding priority assignment and Troubleshooting are the major part of this round.

The Interviewers are very nice and make sure that a comfortable environment during the interview is created to allow the candidate to perform his/her best.

The answers you provide decide the flow of the interview (Each question is layered and will have multiple follow-up questions along with it based on real-time examples).

The Approach to the problem matters and follow-up questions are appreciated.

Questions asked

01. Tell me about yourself.
