Brimma Tech Development Engineer interview questions

First round scheduled for 1 hour - but it went for 3 hours Second round with Architect - 1 hour Third round - design round - Tax Automation design and architecture Fourth round - Manager and HR Final Round - Meeting with Leaders I have cleared all the tech rounds and had a package and other discussions with HR. Then the HR told me to meet the leaders as a final round. But after the final round, they told me that I don't have in-depth knowledge. They haven't provided proper explanation for rejecting me. If I don't have in-depth knowledge, they should have told me after the first round. It clearly shows that these guys do not have enough knowledge / skills to analyze a candidate. I don't think these guys are real professionals. I think they are just doing interviews for eye-wash. I never recommend this company to anyone. They will be wasting your valuable time. During the interviews, they told me that they are looking for people with good attitude. Seriously ???
