The process is effective and efficiently done. I applied online through the company website after which I was asked to give an assessment. Stage 1 was numeracy and literacy test. Numeracy test was pretty straightforward, simple 20 numerical questions and literacy test was a simple case study that required some research but was easy because a sample was provided along with the question. Stage 2 was a short phone call understanding why you want to work at the company, why this particular role, where do I see myself in 5 years and salary expectations. Stage 3 was an interview with director and senior manager consisting of two part, first part was a general chat about myself and what I know about the company, later there was a case study which tests your logical and technical reasoning, purely abstract just to test the way you think and how you rationalise it.
