Almost every position, even if it says something different has to do with sales. They hire people, get a benefit from them and after 3-6 months, they fire them, without exception. I worked at the branch in Mexico City and this happened all the time in all of Rocket's different branches (Linio, Hello Food, Dafiti, Lamudi).
They expect you to work 12 hours a day and the salary is really low. They promise you will grow within the company, which is true. One of my co-workers was promoted from a sales executive to a manager, which required more work and pressure, but his salary remained the same.
If you work here, expect to be fired really fast. 30 people I knew that worked with me were fired after 3 to 6 months of working there.
It was very common for bosses to fire their employees because of personal reasons.
