I applied online. The process took 2 weeks. I interviewed at Sia (New York, NY) in July 2018
Interview
Started with a brief phone screen with behavioral questions. Not the most organized, recruiter forgot who I was.
Preceded onward to an analytical test. It was analyzing the hypothetical quarterly earnings of a company and answering corresponding questions. Upon completing and emailing back the analytical test, I was told I would hear back within two days. Even though I followed up twice over two weeks, Sia Partners completely dropped me and the interviewing process apparently ended there.
Careful investing a lot of time prepping for an interview here, they won't even reciprocate a second.
I had two interviews, one initial screening interview online, and one in person interview. During the in person interview, the interviewer walked through my resume and asked me specific questions regarding certain bullets such as how i had artificial intelligence experience since it was on my skills section.
There was online application, and then a call with human resources, one case study with n + 1, and one for with n + 2. Overall not too hard. Friendly people
4 round interview, one code test
second round is more difficult, will ask more technical question
third round will ask ok your take home test
last round talk with Partner
overall not very difficult
