Own Company Software Engineer, Backend interview questions

Total 3 rounds of technical interview for India location including one with the Director of Nimmetry(acquired by OB). Then HR discussion post which there was no communication from the HR coordinator. Complete silence which is very unprofessional. Doesn't seem to the right place culturally.

Very good and thoughtful process. One introduction interview, then two technical interviews. They were very transparent regarding the job and the entire product. I have eventually got a very good offer, it was a good & more than expected offer.
