A recruiter reached out and set up a technical programming interview. They sent information about what types of questions etc. might be asked during the interview, which was nice. They also sent a link to CoderPad, the website they used to interview me. I practiced using the CoderPad free trial, and while I was practicing, I could test/run my code, so I was expecting to be able to run my code during the interview too. Unfortunately they don't allow you to run your code during the interview, so that threw me for a loop.
Make sure you're prepared for a blackboard-esque (i.e., no testing/running of code) interview, even if it's on a web interface.
