I applied online. The process took 2 months. I interviewed at WisdomTree Investments (New York, NY) in Feb 2018
Interview
1. Technical written questionaries (6 questions mostly on tsql, python)
2. Phone screen interview with hiring manager
3. On-site interview for 2.5 hrs with 9 people
Took over 4 weeks to get final response after interview (everything before that was scheduled within days). Would appreciate earlier feedback (even though I have contacted HR after 2 wks as agreed).
