The first round was a coding interview with 10 questions and a 2-hour time limit. The coding interview had to be completed within two weeks of receiving the email.

The coding interview was pretty straightforward:

• 5 multiple-choice questions to select the right output from given code.
• 5 coding problems: 2 easy string manipulation questions, 2 medium logic-based questions, and 1 hard question on BFS.

I completed 9 out of 10 questions in the given time. I didn't have enough time to complete the BFS question.

Next was the Technical Phone Interview. The interviewer was pretty chill, and the coding questions were simple.
