Smooth interview process. I moved through the stages very quickly until I had the third interview which was with the partner. From then on, things started to slow down. They said they should have made a decision within 2-3 weeks. I sent them a follow up email after this timeframe had passed and they said that the process is still in progress. After another 4 weeks had passed I sent them again a follow up email and they sent me a rejection through the system. Very unprofessional behaviour and such a loss of time and energy.
