Technical Behavioral
The interview process was pretty chill. The interviewers were really nice, welcoming, and friendly. They gave me plenty of time to answer questions, and they asked a good mix of technical and behavioral questions. Some solid studying on JS, HTML, and CSS should be enough for this role. Any experience with SEO and accessibility would be a big plus.

Coding Technical Behavioral
The interview included a take-home coding challenge that tested practical JavaScript web development skills. It was divided into two parts: sorting/processing data and then visually displaying it. I had 3-4 days to complete it. On the actual interview day, I had to go over my code and explain it thoroughly. The interviewers were really nice and made the atmosphere relaxed so I could feel at ease. They also asked some behavioral questions at the end, so make sure you're ready to discuss your previous experiences and what you've contributed.

Coding Technical Presentation
The interview process for the internship wasn't too difficult. I was given a coding challenge to complete over a few days. This challenge involved some basic data processing using JavaScript and then displaying that data using HTML. During the actual interview, I had to explain the code I had already written in depth. Both the interviewer and recruiter were quite friendly. The recruiter even stayed in touch for about six months, even with the COVID-19 situation.
