Behavioral Technical Coding
The interview process consisted of five rounds. First, an HR screening that talked about my background and overall fit. Then, technical and role‑focused interviews with the hiring manager and team lead, talking about my industry experience, systems knowledge, and alignment with the role. I then interviewed with a team member about product and reporting. Next, a conversational round with the Head of Data Operations about expectations, working style, and system expertise. The last round was an in‑office interview with the team lead to confirm role expectations and team fit. I got an offer within 2–3 days. The process was well‑structured and positive. Chris Dobo was supportive, giving timely updates, interview prep guidance, and company culture insights.

Behavioral
I had a really good time interviewing here and Chris was a big part of that. He was super helpful and interested from the start and made sure I knew what was happening at each step. He communicated clearly and openly, making the whole thing feel easy, respectful, and organized. I also noticed everyone else involved was just as professional, supportive, and nice. They all really made a difference. This experience just makes me more excited to start my new job because it really shows the company's great culture, teamwork, and professionalism.

Coding Technical Case Behavioral Other
It started with an OA on Hackerrank which included some basic Probability, ML, and Maths questions. Then there was a 30-min online interview with a trader, mostly motivational, and to check my general understanding of energy markets. After that, it was an Assessment Centre (AC) day in the office, which lasted about 4.5 hours. This involved a prepped case study on some energy market, a live coding assignment in Python, a couple more interviews, and some brainteasers.

Coding Behavioral Case
The interview process started with a Hackerrank assessment covering probability, programming, and statistics, which was quite easy. This was followed by a video chat with a Product Manager where we discussed my interest in energy/commodities and other personal interests. The final stage was an onsite interview with four people. This included a case study that was provided the day before. I also had conversations with traders and HR during the onsite.
