Take the time to prepare but don’t overthink it. Career Karma is a great resource for this. I practiced what I wanted to say a couple of times and jotted down a couple of quick talking points. It was a little nerve-wracking but the reps that interviewed me were easygoing and navigated the call well.
Definitely know some HTML CSS JS basics and the interviewer told me that they are not a 0-100 school, they are a 15-100 school, and they sent a packet of (4) challenges and a career outlook test and another interview scheduled for next week after I’ve finished those, but they are pretty easy :)
The resources here at Career Karma and the CEO kickoff prepared me really well with the right questions to ask. They seem to really like this app and that helps that you’re part of it when it comes to Thinkful. So, just go to the CEO Kickoff and you’ll know just what to ask. Best of luck on your chat with Thinkful!
