This was for the User Interface (C#, Java) role.

I applied on July 8 and received the HackerRank assessment on July 22.

The OA consisted of 10 MCQs on CS fundamentals and 3 coding questions, which I answered in Java. The coding questions were on string manipulations.

After taking the OA, I received an invitation for a phone interview on August 24. I gave the interview on August 31.

I was asked DS and algo questions, along with OS and computer network questions. I was also asked one coding question on base conversion.

The interview was supposed to be for 45 minutes but was extended to 75 minutes.

I received a rejection after one week.
