I applied online. The process took 2 months. I interviewed at BlackRock (New York, NY) in Oct 2017
Interview
Hacker rank screening test followed by a manager screening interview. Actual interview has 4 levels with 3 technical and one manager round. Don't apply if you are over 35. I was reminded multiple times that I was the most senior candidate for the job. Also they advertise as a Data Engineer job requiring Big data Technologies. The team actually use Sybase products. Don't apply if you don't have the skillset. Also people have an aversion for anything Spark or Big Data ish even though they mentioned that as required skills on the requirements. Looks like they plagiarized the requirements form a SV company without bothering to add what exactly they need . Also watch for gotcha technical sounding questions from the managers. Even if you clear the technical rounds, the manager rounds is what matters. Also I exchanged 19 emails with the HR. He didn't call me once in two months of the process. They didn't even bother sending a rejection email till asked.

The interview experience was pretty good. Interviewer was supportive and giving hints to help me tackle any questions but at the end didn't hired me. Also they seemed to be interested at first but they didn't hired anyone from our college which is very sad.
