Was contacted in November to try and get a position from a previous conference, which included me applying for positions, but was not selected for an interview at the conference. Fast forward to march, and was contacted because they found my resume in the data base from my previous submission. Had to submit my resume again, and wait to see if I was selected by the hiring managers to attend the hiring event. Three weeks later I found out I was selected, and had to leave in 4 days. At the Hiring event, I was interviewed by 5 hiring managers, for one hour each, hiring directly for people to work for them. There was a mixture of technical Questions, behavioral questions, and brain teasers. I am electrical engineering, so I was asked questions about SoC architecture, how microprocessors work, semiconductor physics, about past experiences, and the brain teasers included questions to see how you approached tricky questions. At the end of event, the people were given formal letters by the managers if they were selected. I am sure that after people selected their first choice, the other rejected offers would trickle down and go to other qualified candidates in the following week... but that would be the assumption.
