I applied through an employee referral. The process took 2 days. I interviewed at NeenOpal (Bengaluru) in Oct 2021
Interview
I had 4 rounds
1. Telephonic interview with HR about salary expectations and 2 basic SQL questions
2. Screensharing SQL questions with the same HR
3. Three Tasks passed on Pandas, SQL, and Tableau for which they give very little time to complete. They literally asked me to complete it overnight
4. Explain the tasks completed to a senior data scientist. I was rejected in this round for making a small formula mistake
What I liked is, they provide interview feedback always to correct our mistakes. Very few companies do it
