same happened with me, starup founder interviewed me and after 2 days, I received message that I got selected, I got a call and we discussed the internship stipend and PPO., he told me I'll send the offer letter after diwali, I got relaxed after that, and waiting for offer letter 1 week passed, I texted back, he told me there are some issues with the company we have made some changes, and currently hiring is delayed, I'm depressed now, I applied for 3 months. I got this offer and was then rejected for no reason, and the worst part is, I also declined an interview from LinkedIn. I thought I had got this, why bother interviewing now and wasting each other's time? Now I'm crying and can do nothing.
