Mihup Communications interview questions

I sent email to HR applying for the position of ML Scientist. The job was posted by COO at LinkedIn. Receiving no response after around two weeks, I messaged COO. The HR called me for an interview "Parked for any other role". It was a technical discussion round with the VP of engineering, his behaviour was nice and the interview went well. Mainly discussion about my research projects and logical analysis took place. They made me to wait for around one hour after interview, though result was not declared that day. After around one week, they mailed me that I was not selected.
