I got this opportunity by way of employee referral. It has 2 rounds. Every round is an elimination round. Firstly we will get an Email from HR a day before exam containing the exam link. We need to register from the link and take the exam in that particular exam window. After that the results will be declared within a week. Mostly in two days we can expect the 1st round results. After that interview will be scheduled. If we meet their expectations we will be offered the job. Entire process of on boarding takes place in less than 15 days.
