VMware interview questions

They have 4 rounds of process. It starts from basics of statistics to technical interview including language and tool skills like SQL and R. I cleared all rounds, however, they didn't get back to me with a positive or negative feedback. It has been a month now. Given that I was selected, they should have rolled out an offer or at least called that they're closing the process. They wasted my time.

There was an online aptitude test. Then we had to go to the VMWARE building. Over there we had Group Discussion then Email writing and then Group Discussion again(not for all).
