Tipping Point Solutions interview questions

They asked me important questions of the ISD process including having me create a learning objective. I was also asked important ways to get the most out of a workshop to glean the best information.

I was contacted via email to schedule a video interview. Interview had 4 employees ( 1 HR person, and 3 engineers). Felt like it went rather well, received a follow up phone call asking for salary negotiation. We settled on an acceptable range (well below my initial ask, which was part of the initial application). Asked if I could start that same month (they seemed to be really in need of someone to start right away). I told them I could start the beginning of the next month. I was told I should hear back shortly about a possible offer. Never hear back. That was 3 weeks ago. Seemed rude to put me through that second conversation without any follow up. Even an email saying I was not going to get an offer would have sufficed.
