I got to know this job from LinkedIn where company's founder had posted JD. Later he connected me to the HR and got the process started after a week. As I was in Delhi so full process was done on telephone and live coding platform. First round: I was given Hackerearth test link to solve 3 coding problems in 2 hours. I chose Python and did all three in around 1.5 hour. Problems were based on String Manipulation , Tree data structure and Logical thinking. Second round: It was a telephonic round was taken by senior software engineer. Various questions were asked on Python, Django, Docker and mostly on MongoDB. A problem in MongoDB was given to design database schema and to fetch data using queries in minimum possible time.

Fourth round: It was also in the same fashion and CTO took this round, asked a algorithmic question to explain and write code and later asked about the whereabouts, career goals and like things.
