TikTok Software Engineer(Internship) interview questions

Gave assessment which lasted about 40 mins. The assessment was proctored and was hosted on hacker rank. There were about five questions. I am yet to receive any feedback over it.

there are 5 coding problems in OA, it requires me to finish them in 120 mins, but there is no time limitation for every single question. The first two questions are easy, even can be sovled using one line code, third and fourth are both medium, the last is a hard question
