I applied online. I interviewed at Koehler Instrument in July 2015
Interview
The interview process is short. General questions about your courses, about what you can do, what software you can use, any formal working experience. But the process takes long. It took almost two months to get a positive answer. I called them several times, because they told me, I am the NO.2 on their list.
I applied through an employee referral. The process took 1 day. I interviewed at Koehler Instrument (Bohemia, NY) in Mar 2018
Interview
They called you in for an interview, and you speak with the HR manager first. She asks you the general questions you would expect at an interview. Then you get interviewed by the person who is actually hiring you, or you will be working directly under. The interview process was quick and simple.
