I applied in-person. I interviewed at TikTok (Singapore)
Interview
The interview process consisted of two technical rounds, each lasting about one hour.
In the first round, the interviewer was familiar with my resume projects and related technologies, and the communication was smooth and professional.
In the second round, the interviewer was not familiar with the technical background of my projects, the communication was difficult, and the overall interaction felt less constructive.
Interview questions [1]
Question 1
Write down the cross-entropy loss function and explain its formulation.
Super long process, it took more than 5 month for six rounds of interviews. I talked to many people at multiple levels in different time zone, and each one took long time for an outcome. Failed at the final stage due to lack of direct experience in the past, however in the first round of interview it has been said that past experience was not important.
