Vantaggi
Working at IBM as an intern was a great experience, perhaps mostly because it was my first relevant experience in the field. The team I worked in and my supervisor were helful and nice. I received a welcome package with IBM merch on the start of my internship. I thought that was nice! There were also some events that were organized amongst team memebers, or company-wide like barbecue, launch events etc.
Svantaggi
There's a canteen/kitchen that serves lunch everyday. While the food was usually good, I guess I expected it to be covered by IBM since I imagined it a big company, but you pay for the lunch if you eat there, or it is taken out of the salary at the month's end. (Note that I subconscoiusly placed IBM on a similar level as Google, Meta, and the likes, where food and other resources in the office are usually free).
