How do I pick a future employer?

By taking enough time to orientate yourself. Start by listing down what are your ‘need to haves’, followed by ‘nice to haves’, in order to create a list of basic job requirements. When you found yourself a pool of interesting companies, register for Inhousedays or other events. In the end your feeling has to be right, and being ‘inhouse’, meeting the people, seeing yourself walking in that particular office, is what matters the most.
