The interview process consisted of three rounds:

• Online test
• Technical interview
• HR round

The online test lasted for one hour and included 29 multiple-choice questions and 4 coding problems. I recall two of the coding problems involved finding the smallest difference in a continuous number sequence and checking for a balanced bracket sequence.

Following the online test was the technical interview. Unfortunately, I was not able to clear this round. The interviewer noted that, despite answering all questions, my background in Data Structures and Algorithms (DSA) made me not a good fit for the role.
