Total Rounds: 4

Round 1: An online programming test on mettl.com consisting of 2 easy questions and 1 medium question.

• Q1. Solve a postfix expression.
• Q2. A straightforward question to sort the array and find the difference between certain elements.
• Q3. Calculate the mean, median, and mode of a given array of numbers with precision.

Round 2: A technical interview where I discussed my projects and a question based on the application of data structures.

Round 3: A technical round with questions on strings and different variations of the "buy-sell stock" problem.

Round 4: A technical and behavioral round. There weren't programming questions, but we had a discussion on encryption (in messaging apps and video streaming platforms).

Note: I did not have hardcore knowledge of encryption; I only knew what encryption is and where and why it is used. Later, the interviewer explained a few topics on encryption and then asked me questions based on them.
