Ironhack Program Manager Lead interview questions

Have been contacted by one employee of Ironhack and after a few days I had the first call with HR. A few days later I had the second interview with another employee which sounded very positive. Then they literally disappeared. I tried to reach out to them twice because I really liked both the job and the company but they never got back to me. I understand that they are very busy but I would have appreciated at least a rejection template to show professionalism and give minimal feedback to the interviewee. Hopefully they will take this comment as a constructive feedback.
