It took me a couple of weeks before being contacted by the management to have an interview in their company near Rockwell Power Plant Mall. The interview took around 45 mins - 1 hour. Knowing the company's background and its current status as far as the news/internet has access to so that they would see you are interested about the company. The interview includes a behavioral and case portions. If you just be yourself and answer honestly, it will turn out very well. Do not worry about the case because it is answerable but being pressured would not help you so stay relaxed.
