Applied through a general application online. Got a call from a recruiter a couple of days later. The recruiter was nice to talk me through my skills and find a matching job at Wolfram. I got a 30 min technical call after that. Spoke about the project and mathematica language. The interviewer said he should get feedback from hiring manager. I got a task to do in mathematica after that. The cloud note book software is crappy. The company has to improve it. It was a simple task to work on Json in mathematica. A simple google search would get you there. After that hiring manager gave a call to review my code. I don't know what he would be expecting from a first time coder in that language. I did not do things the efficient way because I don't know the concepts involved. It is an interesting language though python would kill it any day. Got reject after this.
