A week after I applied online, HR called and emailed me to set up a phone interview. Like any phone interview, I was asked about my work and education experiences. I was also asked about my salary requirements. At the end of the call, we set up in-person interviews for that same week. I had three one-on-one interviews. The following week, I received a call, and they wanted to bring me back in to meet with senior leadership. Three more one-on-one interviews within that week. The following week, I received an offer. CoreSite hires a third party company to run a thorough background check on you, and a drug test is required. All in all, the interview process went pretty quickly/smoothly. I had a job offer probably three weeks after I applied online.
