At first, it went well...until the CEO appears in the process. Huge ego, needs to show who he is, you can feel his toxicity. We talk about conditions (salary, travels & expenses...), we agreed on everything and he said: ok, I m gonna send you a contract with everything we talked about. I got the contract, it was not the salary we discussed and he played the victim: "we misunderstood..." and so on. Man, I over 40yo, You smell narcissism at 50 meters. you are a scam dear CEO.

Easy not too hard. Study abt the basics then you will pass. Technical about gis stuff like buffer tools and other relevant tools related to the project. Show your interest
