Medical is a simple physical and agility test. For the interview just make sure u know the full job description of what a block operator does.
The job is good so far. Some days are easy and some days are stressful but everyday is a new day. Just listen to the mentors and people training u and dont be a know it all. Job security is fine. We will all be in Jamaica central control eventually and the goal is to qualify as a dispatcher. Operator position will be gone eventually.
