After a great conversation with a recruiter, I spoke with the hiring manager, and both interviews went well. Lots of good signals about culture and what work is like day to day. Then came the technical. Other people on Glassdoor complaining about the complexity of this exercise are not exaggerating. You are told that about four hours is reasonable, and then they send you a project description that is FIFTEEN PARAGRAPHS LONG. Everything else in the interview process is going so well that you push yourself extra hard to nail this. Ultimately, this is the kind of project that a high level college course would allot several weeks for. It is also the same project regardless of what your engineering specialization is. At any rate, I spent about 60 hours on this stupid project and sent it in in a mostly working state. I was pleased to move on to the onsite phase, after all that time and effort. The onsite is completely reasonable, further making the takehome exercise stand out like a sore thumb. After the onsite, despite the recruiter keeping in touch throughout the weeks of interviewing, everything went silent. I was completely ghosted. After everyone seemed so kind and empathetic, and after spending so much time on their completely absurd technical, this was especially devastating. I guess ultimately I dodged a bullet, if this is any indication of how they treat people. Stay far away from these people. They appear sane but are anything but.
