At the end of August, I applied to many micro-enterprises, and then the HR contacted me saying that several hiring managers were interested. I followed up with the group that best matched my background, which was related to planning and control.

Phone Interview In the first round of phone interview, the HR told me that the questions would be classic coding problems, but in reality, it was about designing and implementing some functions of a text editor, somewhat similar to Vim. At first, I felt a bit confused. Later, as requested by the interviewer, I created a basic class that implemented some insert, delete, edit, and print functions. Two days later, I received a notification to join Angsai. Angsai: 1 Question Question + 2 Coding Questions + 1 SD Question Question The interviewer was HM himself, and it consisted of basic standard questions. Coding 1: A bit like Jiu Sanjiu, but with the minimum changed to the maximum. There were two follow-ups: first, what if no other points are allowed inside (similar to San Sanjiu bullying); second, how to handle it if not limited to parallel coordinate axes. The second one didn't require implementation; just discussing the thought process was enough. Coding 2: Sparse matrices, implementing left and right multiplication of matrices and vectors. SD: A system similar to parking management + Uber. Customers call for a car at the parking lot exit and wait. Vehicles need to move between different parking spaces (e.g., charging for maintenance and then parking in a regular parking space without a charger to wait for another car). We discussed what performance metrics could be designed. This Saturday, I received a rejection letter for the system design. Sigh.
