They will invite you through email. The interview process takes around 1 hour and additional technical test. The office is quiet nice and then the IoT is very good and interesting

After submitted CV and got shortlisted, the local unit calls for the first interview, which gives you a head-start actually if you are acceptable for them, to get you ready for the second interview by the Germany counterpart (if the business unit requires). Second interview usually a tougher one if your role is technical. Pay serious attention on it, you know you are good enough if you can pass it.
