Wise interview questions

First there was recruiter call around 30 mins. Asked some background question and some normal basic tech question. Then I interviewed pair programming. Based on pair programming result set the next system design interview. It also went super well. After that recruiter never reached out to me even I asked for follow up multiple times. It was the worst interview in my life, spent couple of weeks to prepare for the interview and also took vacation from office only for interview process. But my recruiter didn't feel anything he should at least respond my email. Very unprofessional.
