I have been through many interviews with other companies, including very drawn out ones for technical roles, and I have to say that none have impressed me as much as my experience with Citrine. I read through the reviews on glassdoor during the interview process, and I suspect that management has taken note of some prior feedback because my touchpoints with everyone were markedly different than many of the reviews here. Notably, all of my conversations with the hiring manager (one of the Vice Presidents) were incredibly well conducted. He offered extensive feedback on my performance and fit. While I became more excited about the prospect of working at Citrine over the interview process, from the beginning I thought the role might be a stretch based on my experience (extensive in an unrelated technology industry, but my educational background is in chemistry). If future roles are a better fit I would not hesitate to work with Citrine and the team there, or recommend friends and colleagues do the same. Stepwise: 1. Initial outreach from company recruiter via LinkedIn. 2. Informal, conversational phone screen and bidirectional Q&A with recruiter. 3. Interview with hiring manager (VP). 4. Take-home challenge consisting of 4 multi-part questions that were highly relevant to the role and industry. It was apparent that a lot of thought was put into these. 5. Skills interview with two machine learning data scientists, each with PhDs in chemical or material science backgrounds. 1 hour with multiple questions and scenarios, some including reference and/or role play to the take home challenge questions. 6. Conversations with hiring manager around feedback, and my personal situation concerning competing offers, timing, and remaining interview steps. 7. Did not proceed further, however the next step was either an Onsite or 4 hours of remote interview with senior leadership in one session.
