What a waste of time and energy.
The full process took several months (6 interviews including a technical interview) between the first and the last interview.
In the last interview, the HR told me that everything is perfect and I would receive an offer in the following days.
It took a month (March 2025) to have a response saying: "sorry but this position is not opened anymore as we changed intern politics in 2025 and we do not hire your kind of profile anymore".
A pure joke.
