Technical
The technical questions asked were pretty standard for a first-round interview. However, the interviewer was really discouraging and unprofessional. When I wasn't sure about some answers, she kept saying things like 'oh my god' and raising her voice instead of helping me or just moving on. It made the whole situation super uncomfortable and messed with my thinking. I feel like interviews should be about testing skills respectfully, especially for people starting their careers. That wasn't my experience, though. I hope future candidates get a better, more professional vibe.

Technical Coding System Design
I recently went through a three-round interview process with Nielsen, which took about two weeks. It started with a technical round via BarRaiser covering SQL, Python, Spark, and general technical skills. Then there was a second technical round with a Nielsen MTS3 person, focusing on SQL, Python, Spark, and system design. The final round was a techno-managerial one with a Senior Engineering Manager, mainly about system design and problem-solving. The interviewers were good and asked relevant stuff, but the HR feedback was bad. They said the feedback was positive after round two, but I never heard anything about round three. It's annoying to spend so much time and effort and then not get any info on how you did. My advice is for the company to give feedback quickly, good or bad, to candidates. This would make the candidate experience better and show they respect our time.

Coding Technical
The first stage was an online assessment with DSA and MCQ questions. After passing that, I had my first interview round which included easy/medium DP and DSA questions, along with internship-related questions. I was selected for the second interview round, which had easy/medium DSA questions. However, I wasn't able to provide the best solution as the interviewer focused solely on the optimal solution rather than the approach. I was given time but couldn't find it. This round also included one SQL query and internship-related questions. Unfortunately, I was rejected after this round.

Input: N = 3, profit[][3] = {{14, 2, 11}, {11, 14, 5}, {14, 3, 10}} Output: 42 Explanation: Open Shop 0 as Food shop. Profit = 14. Open Shop 1 as clothing shop. Profit = 14. Open Shop 2 as Food shop Profit = 14. Therefore, the total profit = 14 + 14 + 14 = 42. Input: N = 2, profit[][3] = {{1, 2, 3}, {1, 4, 6}} Output: 8”
