Met with 5-6 people in a 3-hour timespan (CEO, CTO, VP Ops, General Counsel, etc). Also presented a case study which I spent a decent amount of time preparing for them. The interviews themselves were fine and everyone was nice. However this was about 3 months ago and I NEVER HEARD BACK even after multiple attempts to follow up, check on process, etc. Totally unprofessional and showed a lack of respect for my time (including traveling to NYC & preparing a presentation). Couldn't even spare 1 minute to email me that they weren't moving forward
