Databricks interview questions

First, I get reached out by the recruiter and the initial phone screen was 20-30 minutes long. I made it pretty clear why I was looking for a job. Then I had a technical phone screen with the interview. I did complete the question within 30 minuted. But still there was time left, so the interview asked me to write the iterative version of the solution although I did explain that there will be no improvement in time/space complexity but still on insisting I wrote the iterative solution. Then I hear back from the interview that I did clear the interview and a couple of teams are interested in my profile and one of the managers would like to talk to me before the onsite interview. So I thought it is just an informal call with the manager and so did the recruiter mentioned it. Turns out it is was a managerial round where I was asked what I have been doing for the past 1 year why I am looking for a job. Well, I did explain and answer all the questions and then he happens to explain to me different teams in the data bricks. To my shock the next day I get a rejection mail. When I contact the recruiter asking how come I am seeing a rejection now when I was supposed to be done onsite and the call with the manager was informal. She explains saying it was informal but the manager liked to deep dive whether I am suited for an onsite interview. This is the most horrible experience I had in an interview where I was told we will soon be scheduling onsite and then being told I am rejected based on an informal call? Although from the beginning itself during the first 30 minutes call I have clearly explained why I am looking for a job. I would not interview with data bricks again in my life

Interview process was very smooth. The interviewer was very nice and he walked me through the problem. The interview started at exact time, so that I didn't have to wait extra time.
