I recently went through a three-round interview process with Nielsen, and I was left feeling disappointed and frustrated. The process was lengthy, taking around two weeks to complete, and consisted of: - A technical round with BarRaiser, which focused on SQL, Python, Spark, and technical skills. - A second technical round with a Nielsen team member (MTS3), which covered SQL, Python, Spark, and system design. - A techno-managerial round with a Senior Engineering Manager, where the focus was on system design and problem-solving. While the interviewers were knowledgeable and asked relevant questions, the lack of feedback from the HR team was disappointing. After the second round, I was told that the feedback was positive, but I never received any feedback on the third round. It's frustrating to invest so much time and effort into an interview process, only to be left in the dark about my performance. Advice to the company: Provide timely and constructive feedback to candidates, regardless of the outcome. This will help to improve the candidate experience and show that the company values the time and effort invested in the interview process.

Recruiter kept calling regarding confirmation for the interview since morning . When asked for meeting link he said "I will check with manager and let you know" After multiple mails and continuous call nobody showed up at the interview . The recruiter also got unreachable when the interview timeslot came . Stared at the screen for 45min hoping someone would join then dropped from the call. Zero professionalism . Don't apply ever!

First round is JavaScript plus coding round. Second round is more about system design and data structure. Third round is HM round with VP who asks general questions with little bit technical as well.
