      Junior Data Analyst Interview

      Jul 15, 2021
      Anonymous Interview Candidate
      Barcelona
      No offer
      Negative experience
      Difficult interview

      Application

      I applied through an employee referral. The process took 2 weeks. I interviewed at Perk (Barcelona) in Jul 2021

      Interview

      Excessively long process, no feedback given. Many screenings and lots of SQL queries, process could be shorter for sure. The process was as follows: 1st Interview: 30min call with HR for screening 2nd Interview: 1h call with Senior Data Analyst. Situational questions of the type "What would you do if..." Tech assessment: +10 SQL queries on a dataset of 5 different tables (no ER diagram given). Business Use Case and PowerPoint presentation 3rd Interview: 1h call with Head of Analytics & Head of Data Ops. Basically presenting the business use case + questions. In my opinion, challenging hiring process that I personally enjoyed doing. Nevertheless, it may feel like it is too much and they could definitely shorten the assessment. Also, the fact that no feedback is given once they opt you out of the process is kind of discouraging, since many hours were invested in the process.
