TD interview questions

I went through 3 interviews plus one written test on my data analytics ability. The interviews were with HR, Manager and then finally Senior Manager of my team. It was a very quick process and I got hired right after meeting the Senior Manager. The people there are friendly and it is a corporate culture.

received a referral from a former coworker. Initially the process was very straightforward and included a phone screening and two person interviews - the first with hr and the second with the team, including group head, director and two vice presidents. HR was slow to respond regarding follow up. i did not receive an answer for 3 weeks.
