Had an interview with CEO first for about 15 minutes. He explained about the company and the work culture. He was engaging in the conversation we had. Then there was an interview with two MechE, as discussed earlier, I started talking about my project but they abruptly left in between the meeting, as they had another meeting, after about 5 to 7 minutes. They didnt ask me any questions until then. I waited for any company personal to talk me, checked with the front desk (they werent helpful, though not rude). After ghosting me for at least an hour, a personal came up to me (we had initial convo on LinkedIn) as asked me if I had any questions, I asked him 2 non tech questions. He said he would get back to me.
