Well in my experience, You have to bring a luggage of patience as my final interview process took almost 4 hours in total. I was scheduled at 11PM however, due to busy schedule in the Operation Manager assigned for your final interview need to squeeze in his schedule to meet all his tasks. As an applicant you have to set your mind set to extend your patience, to initially challenge yourself how far you will go just to be part of this company. Ops Manager was very accommodating and professional.
