I applied online. The process took 1 day. I interviewed at HackerRank (Bengaluru) in Aug 2025
Interview
Sharing my experience with hackerrank screening test.
There was 2 coding questions
1. Pyspark - this was good question and very detailed implementation was asked with auto fill IDE (like VS code).
2. SQL - this was also very good question but there is very huge problem with output format something like they needed "0" as 0.00 but due to auto format from background it is not reflecting correctly as "0.00" it was converted ".00" always and because of that my solution was not accepted, my entire logic was correct but due to this type of silly things i was filtered out from screening test.
