Handshake Software Engineer interview questions

Recruiter call followed by tech screen. Same question others have described. I provided a working solution but was rejected for reasons unknown. No feedback was shared. Not a good experience.

Interview Process: 1) OA - easy/med leetcode 2) Technical Phone Interview - Work solo for 1 hour adding requirements of a given take-home assignment for both frontend and backend. Then 1 hour with interviewer to discuss what you have done 3) Hiring Manager Interview - talking about your projects Overall, a simple process. Although, the hiring manager I talked with seemed to be annoyed and was cold. No pleasant introductions, straight to the point.
