The process took 1 week. I interviewed at TikTok in Feb 2022
Interview
interviewer did not care about explaining code, focused on optimization to the extreme....question itself was easy to solve but optimization was hard, discussed the optimization strategies with the interviewer and he helped me figure out the best ways to optimize
Interview questions [1]
Question 1
Answer a question on printing out a string when function is called, based on inputs
Tackling the coding round was intense, kicking off with a question about counting distinct island shapes in a grid. The second challenge involved maximizing a sum without using adjacent elements, which really tested my problem-solving skills. About two minutes in, it hit me — this was a problem I had practiced on prachub.com just days before. The final question required implementing stacks and calculating the streaming median. After the technical rounds and a brief behavioral interview, I received an offer, which I happily accepted.
I applied through a recruiter. I interviewed at TikTok
