Rad AI Software Development Engineer In Test (SDET) interview questions

They were very friendly from the beginning to the end and the whole process was straightforward and I knew what to expect. I believe I delivered a good project to test my skills (even having more than they asked) but I didn't get approved which is fine. The problem is the lack of feedback, it's so frustrating to be blind about what was lacking or where you made a mistake. The rejection mail was just generic "we won't follow through with you in this process"
