I applied through other source. I interviewed at TikTok (Mountain View, CA)
Interview
The recruiter was friendly and easy to talk to. We covered two technical questions—both fairly standard—and one behavioral. Overall, it was a smooth and pleasant screening experience. We walked through each of the questions and then I went through my potential solution and started coding. After I was done, we walked through my code again before submitting.
The interview process consists of 4 rounds. Only the first two rounds are technical.
First asked details about projects described in the resume. Then a typical algorithm coding question lasting about 40 mins.
The general process is more succinct compared to traditional 6 rounds technical interview process.
Interview questions [1]
Question 1
Typical coding algorithm question and some resume discussion.
A technical interview assesses candidates' problem-solving skills, coding proficiency, and knowledge of algorithms and data structures. It often includes whiteboard coding, debugging exercises, and system design questions. Interviewers evaluate communication abilities, logical thinking, and mastery of relevant technologies. Preparation and practice are essential for success.

Question 1
A: They asked me to implement a function that finds the longest substring without repeating characters in a given string. This required understanding of sliding window techniques and hash maps for efficient tracking of characters.
