3 rounds, first is lead, then some peers, then hr. Totally very difficulty, since they hope candicator can work for them, no need to train. So if you are a graduate, that's not good place for you, and also very hard to get offer or their company.

HR phone interview, where the HR rep was super nice and dug relatively deep into my experience and previous work. 1st round interview with Sr. Research Scientist was just alright. Interviewer showed up 5 mins late (sure if happens, no biggie) and gave a very speedy intro of the company. I gave an intro of my experience. Just 1 question on my experience and moved into coding. While coding it was a bit odd the interviewer kept wanting me to change x or y about the code or how I was solving it before I could finish completely. This threw me off a bit, as every other place I've interviewed they let you finish and then follow up if you could do x or y to improve performance, etc. Fairly straight forward stats and A/B to finish.
