I applied to Groww through an employee referral, and the process took over two weeks. I interviewed with Groww on May 7, 2024.

Interview Process

There were four rounds:

• DSA: Consisted of 2 questions.
• System Design: Design an analytics library SDK.
• Android Past Project Discussion
• Hiring Manager

I was rejected in the third round. The interview was conducted by someone referred to as a "GDE Expert," who joined the call 15 minutes late. The discussion began with challenges from past projects, followed by an explanation of current project features from top to bottom. We discussed MVVM, clean architecture, JUnit testing, and benchmarking. Although he asked only one Android question, he seemed rushed to end the session within the next 28 minutes and appeared uninterested in asking further questions. I mentioned during the call that we started late and were closing early, but he indicated he was done from his side. Despite his agreement with most of my explanations, I received negative feedback the next day, which was surprising given that it was a past project discussion round and he seemed unprepared.

HR Feedback:

• DSA Round: Missed one edge case.
• Android Past Project Discussion: Lack of depth in knowledge.

My Feedback: Interviewers should join on time and use the allotted time wisely. Rushing through the interview or closing it within 28-30 minutes prevents a thorough assessment of the candidate's depth of knowledge. Additionally, providing detailed feedback on areas for improvement would be beneficial, as candidates invest their time and effort into the interview process. One-liner feedback does not help in improving their strengths or skills.

The questions included a Linked List and a variation of a Binary Search type question. There was also an Android question on improving app performance and memory leaks. Finally, they asked how you keep yourself updated with Android.
