The goal of this session is to share options you could pursue and resources to get you started. You'll definitely have more questions along the way so don't hesitate to reach out for help.
There isn't one cookie-cutter interview process but more often than not, after a company gets your resumé (through a referral, coffee meeting, or online application), they'll set up a phone screen with you. It's typically 30 minutes, and the goal is to get to know you and see if you communicate well. The next step is an in-person interview that lasts anywhere from a half day to a full day. The interview will be broken up into 1-2 hour chunks where you'll meet several people on the team and do a combination of non-technical and technical interviews.
The non-technical interviews will be soft skill questions about your work style, recounting times when you successfully worked with difficult people, when you made a mistake and how you fixed it, etc. For all of these you want to show how you were able to overcome challenges, make decisions that resulted in a solid product, and be a good team member.
Technical interviews include various coding challenges that mainly focus on algorithms. If it's a front-end job, there might be a couple questions about html/css but most of the questions will be about javascript. Feel free to ask questions and talk out loud while you're solving them so the interviewer gets a sense of your thought process. The best way to prepare for these is practice.
