Application: I applied online. The process took around 2 weeks. The following rounds were involved in interview. 1. HR interview (30 minutes) 2. Technical interview (SQL plus python) (90 minutes) 3. Manager Round (30 minutes) 4. CEO Meetup Interview: The interviewer were very professional. In HR round basis personality related questions, why Wunderflats and some questions about previous company. The second round was technical one where I had a call with Senior Data Engineer and Lead manager. They will provide you test DB and in 90 minutes. This round has 3 sections: 1. Skills you mentioned in resume (30 minutes) 2. Python (30 minutes) 3. SQL (30 minutes) I really like the interview process. The interview went well but due to some bad luck I got rejection email after 2 days. Advice to management: Please provide proper feedback to candidates if they request over email.
