Was contacted via email to schedule a phone interview. Interviewer called me at the wrong time but proceeded to interview. Initial screening consisted of behavioral questions. Then was invited to an in-person interview with Operations Lead and Engineering Lead. Was also interviewed spontaneously by company CEO. More behavioral questions, some situational. Not technically rigorous. Leaving a negative review because the communication following the interview was so poor. I was extended a formal offer with documentation and all, but when I tried to negotiate the start date, HR and my interviewer both ghosted me. I politely reached out multiple times asking for an update but eventually declined the offer when it became clear they weren't responding. They still haven't responded to my last email! I don't think Wintec is very well structured or organized internally. If this is how they treat prospective candidates that they claim they want to bring on, I cannot imagine how they treat their employees.
