Yes, it was.
> I thought their interviews were standardized.
I don't know if you can standardize peoples personalities... The real issue here (in my opinion) was the guy was not a good interviewer.
> Can you tell us more about the experience, and what they asked?
I honestly don't remember, they asked about active record (as I do some web dev), but also stuff related to describe on the spot some SQL queries and why one would be faster than the other. All of that appeared fine, the real issue was our debate related to computer vision (where my research was done). Sorry, I can't really dive more in, but it was probably a year ago.
Oof. I feel like computer vision is a particularly misunderstood field. In a way, it reminds me of statistics - I feel like people purposefully obfuscate things to make their results sound more impressive. The great thing about computer vision is you can almost immediately see through the smoke and mirrors - ask for a live demo. I'm amazed how many people refuse to show me a demo of something that is inherently meant to be viewed.
Did they give you homework challenges? Did you clear those but then bomb the interview?
