Bartronics interview questions

I applied through a recruiter. The process took 5 weeks. I was contacted by a recruiter on LinkedIn and the tech stack caught my attention. After a call with the recruiter, I was asked for a technical phone screen. The screening question was a good mix of algorithms, data structures and design. After clearing technical phone screen, I was invited for on-site interviews. There were 6 interviews excluding recruiter. I requested to spread the interviews over 2 days which was accepted.
