Pros

Good starting pay. The bonus is nice if the company hits earnings. The association solidarista is also a great perk.

Cons

Management in Costa Rica is shambolic. American Managers have a tendency of firing employees on a whim. The rotation rate is around 30%. Promotions are not really based on specific values nor KPIs. They are given based on nepotism. The work culture can be insane, depending on the account you will have no balance. Unless you want to fired.

Pros

Can’t think of any pros

Cons

The culture is toxic. Very hostile between departments to pin blame for an issue on anyone else. The annual goals and PMD process results in employees sabotaging each other to look good to get that promotion and leadership eats it up. Raises are extremely low so staying too long means you’re leaving money on the table.
