Trust me, dont even go to the interviee , they will first conduct a interview via the phone and wil ask couple of questions in order to grt an uderstanding on your work ethic, they will ask what is your expectation as well, after that they will send you a link to your email for an online test. Related to your personality, numeracy and reasoing etc , after that they will give some scenarios and will request to write you an essay, once you submit it , the very next day they will give you a call to come for a one in one interview, once you there they will ask you some logical questions and explain the jobrole the interesting part begins when they say the salary you will probably get a heart attack not because it is too high because it is too low , below the market rate, you would regret why did you even come here. Probably this opportunity is good for freshers who do not have any experience at all and do not have any choice( trust me when i say the salary is low)
