Antech Systems interview questions

Super slow process, took over a month between the day i applied and the day they rejected me after an in-person interview, nice people but cannot help feel led astray as I left both of my interviews feeling very confident and happy with how they went,

Applied online. Received a phone call to schedule an in person interview a day or two after applying. Interviewed by three people at their local office. Was asked to write code on the whiteboard for multiple problems.
