Venmo interview questions

Got a call from a recruiter. He was nice and all. Scheduled an online interview after 2 weeks as the interviewer was busy. The job description said we are not looking for any particular coding language and impostor syndrome etc. The interview started just like this. Interviewer: Hi I am XXX, Can you start coding? Me: OK, will do. The problem was not difficult. I did not sense any major concerns from the interviewer regarding my approach. Last 10 min for the interview to end, Interviewer: Do you have any questions about Venmo? Me : (asked some questions as I had to) Got a reject the next day without any feedback. I asked them if they can provide me any feedback but no response from any. What I read from the experience, If we want you we will call you, email you twice a day but if we don't want you, we will dump you right away with an automated email showing you our culture. Thanks, Venmo.
