Applied online and was contacted by a Lyft recruiter. Phone screen was very basic (20 minutes, motivation, why Lyft etc) and I was quickly scheduled for a second round interview with one of their Data Scientists. Again, interview was a breeze (30 minutes, describe past projects and a quick "business case" where you basically just think aloud about a problem and relevant KPIs). Was again quickly moved along to the take home assignment, which as many people here have noted isn't complex per se but is quite a bit longer than advertised if you want to do it right. I sent them a full powerpoint with presenter notes and 2 Jupyter notebooks for data cleaning and analysis. Received a 2 line rejection email 3 days after handing in my assignment telling me I wasn't technical enough. When I asked for more feedback it turns out what they meant is I didn't comment my code enough and I didn't expand on one aspect they thought was important; so nothing technical but pure domain knowledge actually. To me, a take home assignment is for the company to evaluate technical competency and critical thinking and not so much about having the "right" answer, but I guess not for Lyft. My advice to candidates: steer clear, don't waste your time. My advice to Lyft: use the assignment in a smarter way, or if domain knowledge is an actual prerequisite, make that clear and gear the interviews ahead of the assignment that way, because getting through interviews is a walk in the park and then you expect something very specific from the assignment which isn't very fair to candidates who spend hours working on it.

I interviewed with a recruiter last fall. Since I was graduating in eight months, she said she'd talk to the hiring manager about whether to send technical interviews now or hold off for different openings in the future, and would get back to me in a few days. She never followed up and didn't respond to my emails. Eventually, I got an automated rejection, the subject line literally read "Update on [insert job title]," they hadn't even bothered to fill in the job title. The whole process felt unprofessional.
