Summary

I recently interviewed at Omnissa for MTS2/MTS3 roles, facing LLD, DSA rounds, and system design questions. Despite implementing my solutions, I was rejected, particularly struggling with a regex matching question.

Full Experience

I recently interviewed at Omnissa for the MTS2/MTS3 roles.

OA: LLD question on hackerrank. Given a class design, we need to implement certain methods. Difficulty - Medium

Round1 : DSA Round

  1. Find the sum of all digits in a string.
  2. Implement a stack using vector. Follow up - Using queue
  3. Implement a queue using stack.

Round2: DSA Round

  1. Implement a method that will tell whether the API is fast or slow. API is considered fast if its average response time is less than 500ms.
  2. Balanced Paranthesis
  3. Question based on Regex Matching

Verdict: Reject Was stuck with Question 3. I implemented using vary granular approach, interviewer was looking for inbuilt regex methods.
