Four sets of interviews with a Recruiting Officer, the Hiring Manager, a Senior Level Management- in my case, it was the Chief Technical Officer (CTO) and finally, an interview on salary negotiation with Human Resources Manager. You must pass all stages and then an offer is presented, Usually a probationary period of six months after which you get an employment confirmation letter signed by the Chief Executive Officer

First Written test in general knowledge and a bit of the role you are applying for and oral interviews with the hiring manager and sometimes with senior management. Feedback time might take time.
