Don't waste your time, go apply at another company. They ask for an intense take home (roughly 10 hours) before chatting with any developers. During my final interview I thought I knocked things out of the park on the technical side. I was devastated to get a vague canned email the company did not want to move forward with any positions. Company will dump you and give zero feedback on how to improve, which is unacceptable since they ask for 20 hours of your time when all is said and done. Company did follow up with a specific rejection reason after I asked for clarification. But the details were vague and gave no actionable way to improve. The most disturbing part of the final interview process was the behavioral portion. Maybe the person giving it was having a bad day (not sure). But after making myself vulnerable and sharing a story from my career, I was asked to provide a better example. The person conducting the interview seemed rather keen on getting a specific answer I could not provide. Interviewer was reluctant to provide more details when I asked for clarification on what they wanted to know concerning questions. It felt more like I was on trial for being a witch than an engaging behavior interview. I've done many behavioral interviews over the past decade and never run into a situation like this. Constructive Criticism - If the company is looking for specific niche candidates then conduct a behavior interview before asking someone to complete a take home challenge - Not providing detailed feedback post an intense interview process is not appropriate and generally an industry standard. Not doing this will prevent talent from applying as negative reviews build up and prevent people from re-applying in the future - In interviews don't ask people to define random obscure programming terms. Focus on questions that prove a higher understanding of coding fundamentals and working in teams
