I applied online. The process took 2 months. I interviewed at Notore Chemical Industries (Onne) in May 2022
Interview
Usually a panel consists of the Maintenance Manager, Production Manager, Urea, Ammonia and Utilities Production and Maintenance Superintendents/Supervisors. In addition, there are representatives from the Human Resources Talent Acquisition Division and Security Unit.
For the Mechanical Maintenance Engineers/Technicians interviewed, questions are likely to include ;
A) Giving a brief introduction of yourself (do this by highlighting academic experience/achievement and previous job experience sharing engineering significance to that of the company)
1) Giving a brief summary of your university project highlighting key processes, data and formulas
2) Questions on basic ammonia production process
3) Questions on basic pump types, parts and functions
4) Names and functions of necessary process equipment in a fertilizer production company(e.g. turbines and compressors, valves and their types)
5) Solving a math problem should be expected(e.g. differentiation from first principle or integration)
6)Solving a basic force/ bending moment question from physics or strength of materials
7) Naming the company's core values e.g respect, teamwork, reliability, integrity etc.
P.S>>N.B: Company is changing ownership as at the time of entering this info, so the interview process has a fair probability of evolving from info provided
Interview questions [1]
Question 1
compulsory question: what are the company's core values?...
also basic rotary equipment knowledge:(theoretical and structural). their parts , flow terms and terminologies e.g.
what is NPSH?
what is water hammer effect?
what is cavitation?
types of pump by stage and classification(i.e P.D or centrifugal, single or multi stage , barrel type or volute, horizontal split or vertical split),
types of impeller etc
I interviewed at Notore Chemical Industries (Onne)
Interview
have good knowledge on general engineering principles mostly applied from basic physics and chemistry, it will be a good startpoint to gain confidence as the interview gets more specific to either operations or maintenance .
Interview questions [1]
Question 1
explain principle of car breaks
explain principle of volatility;iy on separation techniques
I applied online. The process took 4 weeks. I interviewed at Notore Chemical Industries (Port Harcourt) in June 2020
Interview
A written test was conducted followed by a panel interview with 4 persons on set. The process took about 3 weeks and a plant tour to their facility in onne rivers state
