I received an employee referral. It took them a week to respond and arrange a telephone interview.

The telephone interview was technical, during which I was asked to code two questions on CoderPad. Following this, I was invited for on-site interviews, which consisted of two technical rounds.

The entire interview process was pleasant and interactive, with all interviewers being very friendly. Although there was a significant delay in their response, their offer was very competitive.
