There are too few front-end interview experiences shared, so I will contribute mine.
2 rounds of coding + 1 round of behavioral questions + 1 round of system design.
1 coding question involved DOM traversal and array flattening.
2 system design questions focused on autocomplete, front-end performance optimization, API interfaces, and front-end engineering, without requiring service or database implementation.
3 coding question involved event emitter and excluding map.
4 behavioral questions included a list of more than 10 questions.
There were no algorithm questions. The coding questions were all in JavaScript, and checking Glassdoor might provide some surprises.
I hope this helps fellow interviewees.
