Interview questions [1]
Question 1
How to conserve the electricity of the room the interview was going on
Very easy fireside chat. No technical interview. For clients mostly simple coding: reverse a string, anagram, impl linked list, basic sql query etc for associates. For sr and manager it may be more advanced.
The interview was primarily technical, concentrating on C#, .NET, SQL, and API concepts. Questions tested understanding of core principles and practical application. The process was straightforward, professional, and focused on technical depth.
I applied online and got a calll back, had 4 rounds in total. first was a behavioral phone call just casual talks about your skills and when can you start working and general questions, then two coding rounds in hackerrank - was asked to code in java although the job was for python and finally HR.
3 rounds of interviews with a technical interview. The technical interview involved questions on Java and sql. They were mildly difficult. The first 2 rounds were not so difficult, lots of situational judgement questions
