Round – 2 (Technical Interview)

This was a 60-minute round where I introduced myself, as did the interviewers, and then we delved into coding questions:

• 1. First Unique character in a string https://leetcode.com/problems/first-unique-character-in-a-string/description/
  2. Compute Snowpac: Same as Trapping Rainwater
  https://www.csestack.org/snow-between-hills-coding-challenge/
  https://leetcode.com/problems/trapping-rain-water/description/
• I solved both questions, from brute force to optimized approaches, and the interviewer was satisfied. I also took the opportunity to ask questions about the company and its work.

I received an opportunity through Naukri when a recruiter reached out, expressing interest in my profile and inviting me to participate in an online assessment. I accepted the opportunity, with the test scheduled for the following day.

Here are some tips based on my experience:

• If you have at least 1 year of experience and are seeking a job change, I highly recommend going through https://takeuforward.org/interviews/strivers-sde-sheet-top-coding-interview-problems/
  and solving each question.
• Additionally, prepare for puzzles, Java, and Spring Boot-related questions. Be ready to discuss the project you’re currently working on and how you tackle challenges when you encounter them.
• If the question level is medium-hard then, try to complete each question in 30 min as rounds 2,3 and 4 will be of 1 hour and in each round you will be asked to solve questions if you complete them on time, then be prepared to answer the follow-up questions.
• Even, If you know the approach to the question, go with brute force, dry run your approach on small test cases, and meanwhile also explain both time and space complexity and then slowly jump to the optimized approach.

About the interview process:

• Each interview consisted of two interviewers and all interviews took place on Coder Pad.
• There were a total of six rounds, with the emphasis on DSA at 70%, puzzles at 20%, and Java and Spring Boot-related questions at 10%.
• My first interview was on March 25th, and I received positive feedback afterwards. Subsequently, my next three rounds were scheduled for March 27th, each spaced two hours apart. Following these, I was scheduled for a Managerial Round on the same day.
• On that day, HR informed me of positive feedback for all my interview rounds.
• Finally, I received the offer letter by April 19th.

Now, let’s delve into each interview round:
