FoodCo Nigeria interview questions

I applied online It was handled by one the Big 4 Audit Firm I was given a case study to present in powerpoint I submitted and was asked to come and present to the employer. I then got email from Foodco scheduling interview with the Management. Then I was asked to come for an onsite. I was given a question and collaborators among the staff. I submitted after 2 days. I was later scheduled to present the findings on my onsite visit to the top Management. I was later asked to meet the MD that happened online too. The MD is very intelligent and so humble. Then I got employment letter after a month I met the MD. The process looks longer but it was so cool ans the HR are so nice too.
