Most UNPROFESSIONAL, AMATEURISH , UNWORTHY and UNETHICAL interview i have ever attended. Got a call from a consultancy after which i attended the interview. Technical and Head of Department interview will be done on same day then they will tell you that client interview will be there. This is the most unprofessional company i have ever seen. After 2 weeks client interview will be done then they will take another 2 weeks for HR interview and then they will tell you that it will take 3 to 4 more weeks to generate offer letter and then they will not send the offer letter. That is what happens with me. So basically they will waste your 2 months in this most irritating, improper and unprofessional interview process. So i suggest Please don't waste your time and don't give their interview only.
