Databricks Software Engineer Intern interview questions

There are four rounds to the interview process: Codesignal, Karat, internal technical, internal behavioural. The Codesignal round consists of an online assessment with 4 questions ranging from easy to medium difficulty. The Karat round is a video interview with an interviewing engineer from Karat. Afterwards, based off of this feedback, Databricks decides if you should proceed to the next round. Next is an internal technical interview. This interview was hard. Expect a leetcode hard problem. Finally, there's an internal behavioural interview with an engineering manager. Pretty typical behavioural - you talk about past projects, experience, why you want to join Databricks. The interview process is really transparent, and the recruiters are responsive

I applied online on September 23 to Databricks from their career website. I got an email with an invitation link to complete an online assessment in code signal within a couple of days. There was a total of 4 questions to be completed. The questions ranged from easy to hard.
