One of them was fairly patient during the interview.

The other one completely ignored you throughout the entire interview and was extremely arrogant.

If you don't meet the CTO during the interview, you probably don't need to think about it anymore.

They will find an excuse and tell you that the CTO had a last-minute meeting and that they will schedule another interview, but there will never actually be another interview.

Additionally, the atmosphere inside the company is dead silent.
