GrayMatter Robotics interview questions

Horrible interview process and extremely no regard or concern for the candidate. The process dragged on from september till december, with periods where communication is extremely slow. I went through 4 virtual rounds, then was called onsite travelling across the country, for 6 more challenges in person. For a candidate spending so much time on the process, the expectation is that the company will be professional in their interview conducting process. I was then informed that everything with my application was good, confirmed my start date as well, and then was told my contract was getting prepared. Then out of the blue I get a call stating that the management informed the team that there was no budget to hire. These kind of budget informations are available beforehand, no business would make such a call at such a last minute and suddenly, or if it was made so suddenly then the management has horrible planning. The CEO comes across as extremely arrogant in the chat as well. Stay away from this company. He also was schedueld for a background check with a C level executive at my previous company but cancelled the call last minute. This reeks of unprofessionalism and no care for someone else's time. The engineers are great to speak to but unfortunately it seems C-Suite level management has no consideration or care for people it employs and I am glad I dodged this bullet.

The interview process was ~2 months in total and 4 rounds. The interview was mainly experience-based. After the recruiter screening I had a technical coding interview that was very easy. Then I had a 1:1 with a team member where we mainly discussed my past experience. The final round was an on-site panel interview where the team looked to understand my system design thinking and problem-solving ability through various sessions testing different aspects of the job (system design, coding, troubleshooting, resume deep dive).
