Question 1
Change some code to make the program more efficient
Phone interview with HR, then a zoom meeting with the hiring manager, then a virtual "on-site" with a few employees. The people were all very nice and it ran smoothly.
I applied through an employee referral. I interviewed at Vertica in Mar 2020
Interview
I had an initial call where the hiring manager went over my resume. Then I had two phone screens (probably because I didn't do so well in the first one). Followed by a virtual on-site where I met and interviewed with 3 members of the team.
