I applied via Recruitment Consulltant and was interviewed before Jan 2024. There was 1 interview round.

Round 1 - Coding Test 

The assignment involved a train booking API.

I was required to explain my thought process and describe the implementation as I progressed. Upon completion, with some extra time available, I proposed and implemented an improved solution: a new method that checks if a train has enough seats for a prospective booking while ensuring that families or groups who wish to stay together are not separated.
