Questions posées lors d’un entretien d’embauche pour Software Developer JavaScript chez Unit4

I received call after a week of applying. First interview was HR interview asking my experience and skills. Second round of interview was scheduled after a week and it consisted of on site interview because the position I applied was subsidiary of unit4 named Prevaro in munich. Then, for third round of interview they sent me coding task which was based on javascript and I will rate these task of medium difficulty level. After this round, I received an invitation to come down to munich office for face to face interview. I was interviewed by project manager, team member , HR person and team lead. After one month of interview , they sent me email that the vacancy is canceled out.The total duration of recruitment process was 8 weeks.It was total waste of time and energy.
