The interview process at LeanData was really great. It was organized and mindful of my time, which was appreciated. What really stood out was how good the people were and how consistent the interviews felt. It seemed like a planned process, not just random chats. I also liked how open they were about everything. They were upfront about what the job entails, where the company is headed, and the challenges. It was a good mix of them showing off the company and making sure we were a good fit for each other.

Technical Behavioral

So, the interview for the Data Analyst job was pretty standard, not too hard or long. First, there was a quick phone chat. Then, I had two more rounds. The first one was a technical interview where they tested my data skills with some hands-on stuff and questions. The second round was with HR, and it was more about behavioral things, talking about the company vibe and what the job entails. It was a solid process, but definitely made me think.

Behavioral Technical Presentation

My interview journey with LeanData for the Customer Support Specialist role began on December 6, 2023. Initially, I spoke with someone, then had an interview with the team manager. Following that, I had three more interviews with team members. Once those were done, I was given a skills assessment to complete. After the assessment, I had to prepare and deliver a presentation on a topic that seemed unrelated to the job, which took me about four days of work. After the presentation, I was told they hired an internal candidate for that position. The whole thing took about a month. In the rejection email, they asked if I was interested in another role, Associate Professional Services Consultant, because I had apparently made a good impression. I got an interview with that team's manager without re-applying. During this interview, I learned that two people had already taken the role I was initially after, and that I would need to present again, this time on a topic that actually made more sense for this new role. After that interview, I went through three more. So, in total, across both roles, I had about 10 interviews over two months. In the end, they said I didn't have enough experience for the job they had asked me to apply for. It felt like a waste of everyone's time due to poor communication.

Coding Technical Behavioral Presentation

It was a pretty long process, about 5-6 stages before the take-home, which wasn't included. It started with a recruiter call asking why I was interested in the company. Then there was a 45-minute coding and algorithm test in JavaScript. After passing that, I got a debrief on the take-home project and some questions I could ask. I had 24 hours to finish the take-home, with a focus on data modeling and optimization. If I passed that, I had to present my project to three senior people. Like before, I was surprised to have to code during this interview, as they asked follow-up questions about my project that required coding. The next steps were a 30-minute culture fit interview and a 1-hour coding and technical interview. They didn't use an online code editor or prompt; the interviewer read the prompt, and I had to use my own editor. These seemed like the final stages, but one interviewer mentioned two more technical rounds, one of which was a one-on-one with a previous interviewer. All the interview questions are available in past reviews.

LeanData Interview Questions

Quoted word for word from LeanData interview reports.

Given a HashMap where keys are strings and values are their weights, implement a function to return a random key based on these weights, like returning 'apple' with 20% probability, 'orange' with 30%, and 'banana' with 50% from the map {{'apple', 2}, {'orange', 3}, {'banana', 5}}.
