A fairly standard process: it starts with a quick call with a recruiter to get to know the candidate and ask basic logistical questions. After that, you’re invited to a coding round that consists of debugging a pre-existing file. If you pass that, you’re invited to a hiring manager interview.
The manager seems cool and easy-going. He spent enough time answering all my questions, although he was visibly a little distracted at the start due to some work-related issue. Overall, I liked the conversation for its relaxed tone and transparency.
After that, if you pass, you’re invited to the onsite stage, 1 hour coding round (LeetCode-style questions that build on each other), a 1-hour system design interview related to the company’s domain, and a behavioral interview. The recruiter prepares you in advance by explaining what to expect and giving some guidance. The behavioral interview didn’t follow a strict STAR format - it was more of a general overview of my career.
After completing everything, I was completely ghosted, even though I tried to follow up with the recruiter by email. I have no idea why it’s so hard to provide even minimal context about how the interview went or whether it makes sense to expect next steps. Because of the ghosting, my overall experience was quite negative.
I applied through a recruiter. The process took 3 weeks. I interviewed at Datavant in Dec 2025
Interview
A recruiter reached out to me on LinkedIn, I sent over my cv and we arranged a hr screening call. That went well and I was through to the debugging stage. I got most of the tests passing and while trying to fix one of the last two I ran out of time. To my surprise I was invited to the next round which was the hiring manager interview and the system design interview. These took place in the one time block. The hiring manager seemed distracted during the call and did not always seem to listen to me. Bar that interview I had a positive experience, this and the standard rejection email sullied the experience

Question 1
Tell us about a project that you worked on where you had the most impact.
I applied online. The process took 2 weeks. I interviewed at Datavant in Jan 2025
Interview
The recruiter was friendly and took the time to explain both verbally and through email what each interview would look like. I felt like they wanted me to be prepared and know what to expect for each interview. They used Coderpad for interviews.
The interviewers were respectful and friendly. Every interview had ~10 minutes at the end to ask the interviewers questions about the company.
Technical Screen (45 minutes): Debugging exercise of some code that was loading and modifying some data from a CSV. There were failing test cases and I was expected to debug the code until they passed. I was offered an option between this and a test through a 3rd party platform that would offer a mix of algorithmic questions. If I'd taken that option the debugging exercise would have taken the algorithmic questions in my virtual onsite.
Hiring Manager Screen: Spoke to manager hiring for the team. This was more of a team matching conversation and I had a lot of time to ask questions about their team and the company.
Virtual Onsite (2.5 hours, I did it all at once but it can be split if you do not have a block that long)
- Algorithmic Questions (1 hr): I went through 3-4 questions that were leetcode style. Finding the optimal solution was not the focus and getting a working solution was generally enough to move on.
- Systems Design Interview (1 hr): I was asked to design a system in the healthcare domain. One interesting thing about this interview was that we did not use any diagramming tools and wrote out the design as markdown in Coderpad.
- Behavioral (30 minutes): I met with a different manager who asked traditional STAR type questions.

Question 1
Debug this code to get the test cases to pass and do some refactoring.
