Optimal Blue interview questions

I received an email from Bridget Drumm thanking me for applying and inviting me to schedule an interview with her via a link. Two minutes later, I receive an email stating this was an error and to disregard the last email. What recruiter makes this type of mistake? It's hard enough being unemployed and being turned down for countless jobs, but then to get an invite only to have it revoked is unbelievably unprofessional. The incompetence of this recruiter is disappointing beyond belief. This error shows the level of employees working at this company and, while it's for the best to not work with employees like this, it's still disappointing that someone like this has a job while I can't even get an interview. Do better Optimal Blue.

4 interviews. First was with HR. Second with a team lead. Third was a panel interview. Fourth was with Product Manager. No tests or oddball questions - simply ensuring the candidate is a good solid fit based on previous job experience. They hired me in an IT role despite not having mortgage industry knowledge which is uncommon for Optimal Blue (on the operations side, and mortgage or FinTech knowledge definitely a huge plus on IT side)
