This review is from an interview I had with the team a month or two ago.
It began with a 60-minute phone interview with an engineer based out of the Bay Area, followed by an on-site at Tinder in West Hollywood.
The on-site involved a small project they wanted me to build. I ran into issues with the laptop I had and also needed credentials for the API. Consequently, I didn't finish the project, but I cared more about enjoying the process than rushing to complete it (probably don't recommend this).
I felt it was a very fair interview. It was one of the first interviews I had during my "interview spree" in finding a new company, so naturally, I was rusty. However, it was good practice for on-sites I later landed at FAANG companies in SF, so I can't complain!
I do remember feeling very, very comfortable there. They take care of you. They treat you to a free catered lunch, and you're free to roam around and grab snacks if you're ever hungry or thirsty.
The major, major downer for me was the lack of diversity in the office. While I appreciated the fairly strong female presence, the lack of POC and the "bro culture" feel was a huge buzzkill.
My advice to an interviewee is to review some of the decisions you make when writing code. If you've been doing it long enough, many paths you take or code you write are practically memorized. You may forget the reason behind them, or you may be leveraging tools that make some processes more simple and seamless.
Just remember that the interviewer's job is to ensure you know what you're doing, and silly mistakes can change their impression of you.
Phone Interview:
Brush up on your iOS basic concepts, i.e., delegation, cell reuse, notifications, classes vs. structs, memory management, async APIs, persistence. Any of these is totally fair game.
On-Site:
Come as you are. The project they give you is nothing more complex than the work you do on a daily basis. You likely won't have some of the tools that you normally use at your office, so review a lot of the iOS basics, especially if your team is using Rx, IGListKit, etc.
