Databricks Software Engineer interview questions

Very bad interview process. Went for onsite and then received a take home assignment. After everything was cleared, they requested me to provide three references from current colleagues. I waited for like almost 3 weeks and they told me that due to current situation they will not move forward. Very terrible interview process. I wasted 2 months of my time for doing nothing. Everything went well but they hesitate at the very last steps and decided not to move forward? If they decided not to move forward after the onsite then they should express it directly and not to waste people's time for nothing.

The hiring process consisted of an introductory interview (30 minutes), followed by two technical interviews (1 hour each). The first technical interview was performed by the third-party Karat, to establish base-line programming ability. The second technical interview was performed in-house and was effectively a poor imitation of the Karat process - it was described as a second-round technical interview (requiring some familiarity with the Databricks product) but consisted of the same content as the first-round interview, albeit with a much worse question set. It is also worth noting that the position advertised was for backend, but the Databricks interviewer was a frontend engineer and unfamiliar with the language used during the interview. The programming language "choice" was also criticised despite being required for the position.
