I went through 4 stages of interview process: initial HR interview, a take home SQL test, an interview with a team member and the last round which included 3 meetings (another team member, an HR partner and a test case presentation) The SQL test was medium hard. The business case was considerably harder, as it required good presentation skills and visualization experience. The people I talked to were all very nice to me. The rest of the interviews included on point practical experience and soft skills questions. The company, however, never replied to me after the last round.
