For trainees: We don’t think working from home too much is beneficial during the early stages of your training: after all, you can learn a lot from your colleagues (even just by sharing an office with them).
But, in general, working from home is totally normal for us. Most people at IDEENHAUS take a hybrid approach: a couple of days each week in the office and the rest of the time at home. Depending on the project and task at hand, it might make more sense to work from the office or to work from home.
