**Interview Review**
I applied online in December and received confirmation toward the end of the month. After several follow-ups, I had my first round in January. The tech interview was an hour-long Python coding challenge on API integration, followed by a system design for DWH and a 5-part SQL question. After that, I moved to a hiring manager interview focused on my previous experience and finally had a behavioral interview with the Director of Analytics. Unfortunately, the interview process was disorganized. The interviewer was late and asked some odd questions. Despite what seemed like a good conversation, I received a generic rejection email the next day, which was disappointing. Given the time I invested, I expected at least some feedback rather than a robotic email response.

Entrevista
First stage: speaking with the HR person
Second stage: technical interview
Third stage: culture fit interview
I only got to the second stage. I think the overall interview process was lean and fast, they don't waste too much time. The technical interview was not that difficult, but despite completing all tests with time to spare and confirmed by the interview that the solutions are correctly. The feedback was quite negative from the rejection email. I believe the interviewers wasn't communicating well and feed back the right messages during the interview process. I'm guessing probably you need a bit of luck here really.
