OnDeck Software Engineer interview questions

I had a phone call with the recruiter, who gave an introduction to the company. Later I did a phone screen with one of the engineers at the company, which went well enough. I got through to the in person interview where I was interviewed by a bunch of software engineers. It was mostly white boarding exercises. Some were easy, and some where challenging. The people interviewing me were friendly and were helpful during the interview. Then one of the recruiters gave me a tour around the office. I have to say, the people working there don't look as happy as they put up on their website. They all looked kind of depressed or angry. Another red flag for me was when they showed me the pantry. The furnishings looked nice, but it looked very bare when it came to snacks in the bins and the shelves. The company extended an offer to me, but I declined it. I got a strange feeling about the company. And in any case, I received much more generous offers from other companies, so I decided to go with someone else.

The interview process was standard. Two phone screens before they brought me in for an onsite. The phone screens were not particularly difficult, just high level algorithmic questions. At no point in the interview process did they ask any "gotcha" algorithms questions. For the onsite, they flew me out and put me up in a nice hotel. The location was very close to their headquarters making it convenient for the day of. The onsite was very pleasant and I liked the team. I was pretty excited about the whole thing until the offer stage. At the beginning of the process, they said they likely could not meet my ask, but that they would be able to meet my current salary. Unfortunately the actual offer was 22k less than I make now, non-negotiable. Of course with all things non-negotiable, when I said no they said they would see what they could do. Two weeks go by and they say they can't improve their offer because I would be making more than their most senior engineers. What this says to me is that they are grossly underpaying their staff so I turned them down.
