Behavioral Technical Presentation
This interview process stood out in what is currently an awful job market. First 2 rounds were within a week of each other and then 2 months of radio silence. They then reached out for the Partner round but then had to reschedule 3 times. By the time I got to the interview, the Partner didn't seem to know anything about my background. Second question in, she didn't like the kind of experience I had and I could tell I wasn't getting an offer. I decided to just try to enjoy the conversation but that was hard after she continued to discount my previous experience. All in all, they clearly don't communicate with each other on candidates.

Behavioral Case Presentation
The interview process was pleasant, with 4 interviews that flowed smoothly and quickly. The first was a classic HR motivational interview with a short English exchange. The second was with a senior consultant, involving a case study where precise answers weren't expected, but good reasoning was. A third interview with a manager challenged my motivations and specific interests in the business unit. The final in-person interview was with a Partner, mainly focused on fit, with no traps.

Technical Coding
I had an initial call with HR, and then a subsequent call with a consultant. Both individuals were pleasant. The second stage involved a shared screen SQL interview. The SQL problems were generally considered easy to medium in difficulty, but the time constraint was tight, with only 20 minutes allocated to answer four questions. Each question involved multiple tables, and for the first question, there were four tables. A significant portion of my time was spent understanding the relationships between these tables to perform the necessary joins. This aspect, more than the SQL logic itself, seemed to be the most challenging part. Essentially, the SQL test appeared to be more of a speed assessment focused on quickly comprehending data structures and question requirements rather than pure problem-solving skills.

System Design Technical
The interview process had 3 rounds. It was one of the worst interviews. Two people, both named Singh from their Mumbai office, kept interrupting me when I answered. It seemed like my correct answers hurt their ego, leading them to interrupt more. They scheduled a 30-minute system design round, which was pathetic. In every round, I heard "we are out of time." I really advise against joining this organization.
