I went on an interview yesterday afternoon and met with 4 people at the firm. I met with the first 2 together, and the second 2 individually. I should send each one a thank you note, right?
Also, they are interviewing for the same position for the next two weeks. Should I send the notes tomorrow so they receive them Monday and I stay at least somewhat fresh in their minds, or should I send them today (and they will receive them tomorrow)?
