I applied through college or university. The process took 3 weeks. I interviewed at TikTok (San Jose, CA) in Oct 2023
Interview
The process was smooth overall. But extremely bad respect for interviewees. I got through all 3 rounds but they cancelled my call with the HR for discussing compensation just 1 hour before the call. Got no feedback as well got ghosted. All three rounds were similar 2 technical with devs and 1 with hiring manager consisting of resume dive, regular ml questions and a leetcode question.
