Spark Eighteen interview questions

Their are 3 technical rounds and 1 HR round (Screening round of 30 min). My profile was being forwarded by a recruiting agency after an initial technical screening. Frankly speaking the interviewer doesn't know the parameters on which to gauge the candidate. Also the interview was for the role of QA lead but they declined it saying that they need more of a QA manager. They simply don't know what profile to hire. They also kept me on hold for 10 days. Simply speaking the CTO of the company is confused on whether they need a QA manager or a QA lead. My humble request you all to please be aware and be cautious while giving the interview as it is all a waste of time.
