The initial phone screen lasted 45 minutes and involved simple questions, primarily focusing on JavaScript concepts such as prototype inheritance and event bubbling.

The on-site interview ran from 10 AM to 4 PM. Every hour, two interviewers met with me and asked different questions, which included a lunch break.

The interview topics covered:

• 1 algorithm question
• 2 design questions
• 2 "tech taste" questions

However, I felt some of the "tech taste" questions were repetitive. For instance, one question asked how I would handle a situation where my team uses a different framework than my preference.

Overall, the interviewers were kind and professional.
