I applied online. The process took 1 week. I interviewed at KeyValue Software Systems in Jan 2021
Interview
Applied Online.
Called me telling my resume was shortlisted.
Had 2 technical rounds based on DBMS, DS and Algo.
One HR round.
1st round :
Had 5 to 6 programming qs ( easy ) and some other qs based on DBMS, Microservice architecture etc. First round was easy. Took just above 1 hour. Was able to ans all except 1 theory question.
2nd round :
2 programming questions. And one question to build a DB architecture based on given data.
Took 1.5 hours. 1st programming qs was easy, 2nd one was hard and DB q was moderate. The interview would really push you positively to get to the final ans and that is a good thing.
Got the correct solutions for all 3 but took some time.
HR Round:
Took around 1.5 hours. Questions about yourself and simple managerial questions.
The whole process took around 1 week. Got the offer the next day after HR Round.
