I have been in software engineering for more than 13 years, have interviewed and hired many people in that time…

Never once did I look at any portfolio. Actually, no one had any they wanted to show!

After screening the CV, they got a 1 hour first round for cultural fit and technical foundations, a simple take home exercise (e.g. build a service that sends emails), in the second round they had to go through their code and justify their choices and in the second part the had to code review the bad submission of a former applicant and in the third part they had to draw up how they‘d extend and embed that service in a microservice landscape.

2 rounds. Never had a „mishire“. Hiring is that easy.
