The job application process was weird. I was given an OA link which had 10 question 6 ML based MCQ's and 4 coding question containing 1 CP and 3 ML based where I had to complete helper functions for implementing gradient descent, Decision Tree from scratch. I cleared them and had 3 set of interview in a week, tech, domain and hiring manager. But the interviews were very weird, the first interviewer asked me to implement an API for some query based system and improving upon that using some constraints. I was not expecting this. In the 2nd round I was asked to implement a whole classification problem from scratch in 30 mins, I dont know what was expected and the guy was intimidating to talk to and made me nervous. He kept grilling me and caused me to mix up my concepts and confused me. After the interview I was relieved that the hellish round was over. I was certain of getting rejected and received a call the next day about the same.
