First you need to submit your resume to the HR. If you are qualified and/or there is a job opening, the HR will invite you to have examination. The examination is different based on the position you are applying for. Usually, you will have an examination containing english and logical questions. Then you will be asked to answer an online personality examination. After the examination, you will have to undergo an interview with your respective supervisor. If the supervisor liked you, you will be asked to have an interview with the boss, and if not, they will just call you again if you are the most qualified among the other candidates.
