BillionToOne interview questions

I had a truly awful experience (worst of my career) interviewing for the head of marketing role at B2One. I met with the hiring manager, Shan Riku, and was asked to present a portfolio onepager. She didn't take the time to introduce herself or tell me about the company and instead we dived into the presentation after briefly introducing myself. Within my portfolio, I included my most recent experience delivering new patient growth for a series b telehealth start up which led to 3.5K new patients and a reduced CAC of -55%. As is typical of most early stage, VC-backed start ups, we had negative unit economics (ie making a loss on each new patient) with a strategy to increase LTV by reducing the cost of care over time. Within minutes she became fixated on the fact that CAC was higher than LTV (despite a huge reduction achieved through many months of hard work and applied best practices) and struggled to understand how this was acceptable. Then, she asked if I was still at the company (I was part of a 10% reduction in workforce early this year) and made me feel as though my contribution was directly the reason for the company's financial misfortunes. This happened approximately 10 minutes into the interview!  I tried explaining that we were reporting CAC/LTV progress at board level and had a clear operational strategy to reduce the cost of care. She seemed unwilling to listen and had already made her judgement that my experience was bad. She even said "let me ask this, because I'm trying to give you the benefit of doubt."—I was flabbergasted! I previously worked at Google for 4 years and know for sure that I delivered exceptional work. Plus, the leadership team has kindly left the door open in case their business bounced back following the economic downturn. After I had finished presenting, she asked if I had any questions for her. I was so desperate to get off the call that I initially said "no" I don't have anything in particular. When she looked offended I hurried made up something vague about her team's structure and success metrics. After the call ended, my husband asked me how it went, and I cried. I have never had the value of my work called into question like this and made to feel disrespected in this way. I originally had a second interview with someone in her team scheduled for the next day but within an hour I received a templated email saying they were no longer moving forward with my candidacy. This email arrived 5 minutes before another interview—luckily I was able to keep my cool for that one. I'm sharing this review so that others can know what to expect if they are considering interviewing and also in the hope their HR team can provide interview training for inexperienced managers. I expect much better from humanity in general but especially from employees at a company of this calibre and funding level. 

I did a remote interview, and then I passed the online detail-oriented test. I got offered to do an on-site interview with a skill test. The skill test was conducted in the lab and it was pipetting technique. I didn't know how to use a pipet and the interviewer taught me. The point is to see detail-oriented skill, not if you are good at pipetting.
