The interview process consisted of three parts - HR call, interview with future team lead + colleague (incl. case study) + interview with team lead´s manager. Two short additional calls upon my request to clarify open questions. The case study task was quite comprehensive but gave me a good idea about what my daily tasks could look like. The whole process was above-average professional, quick and friendly. Great spirit and I could really feel the passion every colleague has for sustainability and for making people join the time that are like-minded.
