Instead of giving a technical quiz and allowing the person some time to come of with answers and response appropriately. Technical questions are demanded of you right than and there to evaluate your technical knowledge. Not just your basic questions with a few here and there gotchas or have to think a little. But what is the equation for the beta gain of an NPN transistor. Which is almost never used for the current job. This is not how my interview was run luckily, but is how they are going now with a new program manager. My interview I thought at the time was very professional and they had a desire to bring me on. Along with promise career movement after the hire on process and work evaluation. Which after new management no longer existed. So be warned of this.
