I interviewed at this company twice and got to the last round both times but had no offer. Process was exact same both times: (1) phone screen (2) manager interview (3) panel interview - 45 min design a link shortener from scratch + 45min work historical drilldown. Personally, I think they are hiring for devops/integration engineers not full-stack engineers. They kept asking me about server side optimizations and cluster networks and things I've never dealt with once in the last 15 years of full-stack software development. I have nothing against the company but I just don't get why their questions were so irrelevant to full-stack. It's like you're applying for a house electrician job and of the 1000s of relevant issues they could have asked you they instead ask you about how to config a power plant that delivers electricity to the house.
