SiMa.ai interview questions

I applied on their company careers site. Got shortlisted and the first round was scheduled in 10 days since I applied. The hiring manager, gone thru my resume and discussed the projects I listed. Couple of technical questions related to the project were asked and I answered them correctly. He sounded positive and hinted for next round. Then was completely ghosted for 2 months and got a rejection mail.

First round was an intro call with hiring manager to discuss skills listed on the resume. The next round was related to ML Hardware implementations particularly how the convolution is implemented in accelerator.
