Ventajas
you could work remotely ( once or two times a week), and you could have a balance between life and work.
Desventajas
The managing style is highly hierarchical. The manager not necessary are very aware of the state of the art techniques ( even not familiar with the field), yet they would micro-manage every step of you. Lack of knowledge even on very basic practices in domains such as computer science, machine learning, or data science. Minor: There is a mismatch between what is advertised on their web page, and what they would offer you in reality. As an engineer, you are not equipped with high-end laptops. You are not going to have an workstation or a stationary desk at work (only a laptop). As a temporary employee, you have no new year bonus or any benefit as a permanent employee. If you are not an EU citizen you will mainly get an L permit to work in Switzerland for a temporary position which is not a good permit.
