LineStream Technologies Control R&D Engineer interview questions

Approached on LinkedIn by company's Operation Manager.. After passing the initial phone screening, I got 2 more phone interviews with the lead and field application engineers. I think that they were performing an initial triage. After that I had a call with CTO and CEO. The phone call with the CTO seemed ridiculous, as his questions seemed superficial, ignorant and he suffered from a really bad English (I mean REALLY). The CEO had a brief behavioral call with me. Two weeks later he was calling me on the phone and kept leaving desperate please to 'connect' Eventually, he made me an 'offer' Bottom line - stay away from this crowd! Yet another fishy start-up with press gang recruitment habits.
