Hach Company interview questions

Pre-screening, then 3 interview round. Started as a great experience, then had to wait more then a month and repeted emails to figure out if I'm hired. Also, I dont understand why I have to write 30 words, but this is a filler.

Great interview process. Extremely thorough, carefully selected panels for interviews, timely and organized. Panelists asked great questions, were encouraged to answer difficult questions and provided a lot of insight for the interviewee.
