Came to know about interview drive via job portals. Was called to be available on one of the weekend. Process was smooth but slow. It was Aptitude, Face to face and then final round

It consisted of an Apptitude test which had 10 questions to be solved in 30 mins followed by an interview round. I cleared the interview and was called at main office in Andheri. It was also a technical interview. After the interview HR told me you could leave for the day and will let you know by tomorrow. The tomorrow did not came and HR was on leave. Atleast have some courtesy to mention to the candidate via email or text. I tried calling for the followup and no answer for one week. After a week they tell you your not selected for the candidature. Wasted my time and energy for an entire week. Please don't waste time applying for this company. No product based company does like this. Shame on IT industry
