J'ai postulé en ligne. J'ai passé un entretien chez ByteDance (Los Angeles, CA) en oct. 2023
Entretien
It is a first-round video interview for a research scientist position at Bytedance. I am a PhD new graduate major in ECE, and I apply this position via a referral. The interview questions are not hard, but unfortunately I did not enter into the second round, and the HR cannot provide any feedback.

Question 1
The first question is to find the shortest path for a knight from start location to the destination location in a square map. The knight has two types of movement, which are specified in the problem statement. The second problem is to implement a binary search to find the target number in an array without redundant elements. The next follow up question is to search in an array with redundant elements. The final follow up is about how to optimize the code to reduce the total number of comparison operations.
