Real, anonymous reports from people who interviewed for Data Scientist at Upstart, newest first and distilled into what to expect across the loop.
After an initial recruiter screen, I was told the next step would be a fairly straightforward conversation with the hiring manager with just one technical question at the end. That’s not how it played out at all for me: the hiring-manager discussion turned into a rapid sequence of introductions followed by a deep dive into technical statistics, and I had to handle some difficult mental-math style questions with a theory-heavy vibe. The interviewer moved extremely quickly and when I was unclear or my interpretation drifted, it didn’t feel like there was much helpful clarification to pull me back.
After a recruiter conversation, I expected the process to keep moving, especially since I’d been told I was a good fit. Instead, I experienced a long silence that felt disconnected from how seriously the role was being pursued.
The interview process typically starts with an HR screen followed by multiple technical rounds, including a remote onsite. Candidates often experience delays and communication gaps, leading to a prolonged timeline that can stretch from weeks to months.
Interviews heavily emphasize statistics and probability, with candidates facing challenging questions that require deep understanding and quick mental math. Expect to engage with probability puzzles and statistical reasoning throughout the process.
Candidates are expected to demonstrate coding skills, often involving Python and data manipulation tasks, with a focus on practical applications rather than just theoretical knowledge. The coding rounds can feel fast-paced and may interrupt the flow of problem-solving.
The onsite interviews are described as the most intense part of the process, combining various problem types, including algorithmic and statistical challenges. Candidates report feeling mentally drained due to the demanding nature of the exercises.
Candidates frequently report issues with communication from the hiring team, including unclear next steps and delays in scheduling. This can lead to frustration and a feeling of being undervalued during the interview process.
The bar for technical fluency is perceived as high, with candidates needing to articulate their reasoning clearly and handle complex questions under pressure. Many candidates felt the pace of interviews left little room for recovery when misunderstandings occurred.
