During the interview for my current job (Machine Learning & Deep Learning Scientist), I didn't get any theoretical questions on machine learning, but only questions on my projects. I didn't study machine learning per say, I followed dozens of online courses but no diploma in this exact field, and my last job was in traditional software engineering. Despite this, I managed to do two small projects (one of music genre recognition [1] on my own iTunes library, and one of eye motion recognition [2]). For both I had published the code on my GitHub, and written a small Medium article to expose the problem I was trying to solve, the data available, the issues I faced and how I overcame them. I personally believe that this is all the recruiter wanted to know, and why I encourage interns and candidates to work on their side projects.
