It was a face to face round and both the round held on same day. I clear both the round and received a mail for Pre-Offer Document requested. But when i tried to upload the documents it showing invalid pan on their site but my pan details was correct even i sent the pan detail over the mail to HR but there were no response.

First it was intro followed by list questions like sort and largest in list. Next they asked networking related questions like fi server blade and rack related . Sorting different types like bubble sort and quick sort
