Round 1: Coding Round

Round 2: Technical Interview round 1

This round was of 1 hr. The interviewer started with his introduction, then mine. Then he directly jumped to coding problems.

• I started with the brute force approach. Then he asked to optimize it and gave me a hint to try using the same array as a map. Then I came to a solution, wrote the code, and luckily passed all the cases that the interviewer was looking for.

• I struggled with the approach first, But we discussed and arrived at a soln. Since time was limited, I wrote the function only and dry-run the cases. He told me that he always asked this question though he knows the time limit to check how close a candidate reaches to a solution.

Round 3: Technical  Interview round 2

This round was also 1 hr long. Again interviewer started with his intro then asked me to introduce myself. He asked me to explain my internship project in brief then we moved on to coding problems.

• https://www.geeksforgeeks.org/check-for-majority-element-in-a-sorted-array/
