3 phone interviews - 1. 1st interview tested basic understanding of RF concepts 2. 2nd interview for gauging additional scripting skillset 3. 3rd interview provided the idea to the daily jobs I will be doing if I get hired.

I had applied online to this position. Had one phone interview from the hiring manager which went on for half hour. Was asked basic questions on RF fundamentals and VLSI basics. They took more than 2weeks to give a reply.
