Traveling for interviews requires time and money, but some expenses may be covered by the hiring institutions/clinics and may include your spouse or significant other.
Keep this in mind when scheduling rotations and budgeting finances.
Strategically schedule your interviews to minimize travel and expense if possible.
By scheduling most interviews within a two-month period in the fall/winter of PGY6, any job offers that are made will be within a few-week window, giving you the chance to compare and negotiate accordingly.
Ideally, your goal would be to have several job offers presented within 2–4 weeks of each other.
