SAP Labs Interview Experience for SDE

The selection process consisted of 1 online round and 3 rounds of interviews. After this, 2 students were selected, and I was happy to be one of them!

Round 1: Online Assessment

There were 2 DSA questions, and the time given was 45 minutes. The level of the questions was easy to medium, but the main constraint was time. Candidates who submitted after 20 minutes were not shortlisted. Also, the use of STL functions was not permitted. Therefore, you were expected to solve the questions quickly.

Round 2: Technical Interview 1

This was a technical round. The interview started with the interviewer's introduction, followed by the candidate's. The following questions on OOPs were asked:

• What is object-oriented programming?

After this, the interview moved to the DSA part. I was asked to brainstorm and implement:

The other phase was related to projects mentioned in the resume.

Round 3: Technical Interview 2

The interviewer first gave his introduction. He asked me the following questions:

• Introduce yourself

After this, I was asked to give a brief description of my projects. Further, I was asked to explain all sorting algorithms with their time complexity. I was also asked to take an example of merge sort and dry run it. Further, two codes were presented, and I was asked about their time complexity. The following questions were also asked:
