Invitae Senior Full Stack Developer interview questions

First meeting with recruiter, then a phone screen, and finally a onsite interview. After finishing the first two steps and getting through, Invitae pressured me to do the final onsite ASAP. I sent my availability and the night before the interview they sent me the materials to prepare. A few hours after sending it to me, they tell me they are canceling the interview because a internal personal applied for the job and they are giving it to them. What a waste and total disregard for my time. They could have told me this instead of pressuring me to do the interview ASAP. I spent hours studying for the final interview for NOTHING.
