I applied through an employee referral.

Interview Process

I received a response approximately 6 months after submitting my application. The HR team first shared a Google Form requesting my basic academic details along with my resume. After submitting it, a short briefing session was conducted over Google Meet with the HR and other candidates, where the overall process was explained. Around a month later, I received a phone call from HR to confirm my availability for the interviews. Initially, both interview rounds were scheduled on the same day, but HR later rescheduled them. My first interview took place on 9th October, followed by the second interview on 10th October. Finally, I received another call from HR with the result. Overall, the process was quite extended, but communication from HR was clear whenever updates were available.
