Very unpleasant, interviewer looked distracted and cut me off when I couldn't answer the question in set time. Ended interview early very rudely. I hope that not all interviews at this company are like this.

First is a recruiter screening and a take home coding test which is a satellite configuration optimization problem based on certain angle/signal beam constraints. Next is a coding round (1 leetcode medium). After that is an onsite where you have to present about a project you worked on, followed by several 1-1 interviews where they go over your background.
