Pretty trite interview process that that felt like rhetoric from an example of what technical hiring managers have always done... ask some silly riddles with zero attempt to suss out if a candidate can perform the _actual_ work that the role requires. After ending my technical interview, I had zero confidence that I'd be a good fit for the role, or even what they were looking for. All we covered was contrived hypotheticals.
For future interviewees (and interviewers for that matter), I didn't receive an offer, but had I, I would have either a) turned it down on the experience of this process alone, or b) requested another interview, so I could feel confident that I'd be stepping into a role that was a good fit, something I didn't gain from the interview at all.
