Ascensus Lead Designer interview questions

I interviewed at Ascensus last year. According to their in-house recruiter who contacted me for the job initially, I did amazing through all the rounds. He informed me after the final round that they will be working on the offer. Everything was okay up until I received a strange request to get in a call for 15 mins quite early in the morning. The call got stranger by the minute as this person rushed through some questions and ended the call abruptly. That was the last I heard from the recruiter. And come to know later, he left the firm right that week. Lame excuse to ghost someone like this. Such a shame wasting people's time like this.
