Instabase Software Engineer interview questions

Call with the recruiter. First round with hiring manager and was moved to the second round. Virtual Onsite 4 interviewers. Overall impression is that they are pretty disorganized. They rescheduled my interview and even that interviewer was late to my interview. I was notified almost immediately after that rescheduled interview that they would not move forward. I believe they had already made a decision to not go forward before my last interview that got rescheduled. Overall don't think the process was very transparent.

I didn't pass the OA although I got more that 810 points in the codesignal. Question 1, 2, 4 are really easy. Most of them can be solved by using hashmap; howver, question 3 is slightly hard.
