Someone should please help with the nature of this job how hard is this job cause i know insurance hardly sells in nigeria... How much do they pay? .. Is it worth attending?... What are their likely interview questions?

If you don't know enough to know insurance is hot cake in Nigeria presently, don't go for the interview.
Insurance has moved away from B2C to B2B now so if you can't handle B2B, don't get yourself frustrated with unrealistic targets. Zenith Insurance pays well if you can work your socks off and can climb up the ladder to a senior marketing executive. I know a Senior marketing executive in Zenith insurance with about 4 - 5M salary per annum. Minus sales bonus.
So if youvare ready to roll your sleeves and get dirty. You will enjoy it. Its not a walk in the park tho. Its not the typw of job you take because you just want to collect salary. Lmaoo

Can someone with practical knowledge help me out here pleeaaassse
