I applied via Company Website and was interviewed in May 2024. There was 1 interview round.
The interviewer was a team Lead Engineer. He first asked me a few questions about database fundamentals (Cluster Index, Composite Index, ACID, etc). Then he presented me with a coding question on codility (LC Hard String question). He was very helpful during the interview and nudged me towards the right direction when I got stuck.
