I interviewed for forensics. They told me to rent a car because they wanted me to interview at various sites. Most forensics programs have an academic center (where the dept is) and other satellite locations such as a jail or forensics inpatient unit which is usually about an hr (or even more depending on the program) away. They wanted me to go to both locations for the interview, and public transportation did not exist between OHSU and the jail. So they told me to rent a car.
(Well just my luck, I rent a car for $200 so I can drive to the jail, and the guy I'm supposed to interview with is on vacation. Then on the drive back, because I couldn't find parking for 40 minutes, I missed another interview)
I don't think you'll have the bad luck I had. The parking situation was horrendous. The dept even admitted the hospital was having a parking problem since a new building was recently added. The program director told me they'd have a parking spot for me at a specific garage, but when I got there the parking attendent didn't know what I was talking about & wouldn't let me park there.
So yeah--you'll probably be better off using a cab. The city doesn't have many taxis driving around. Its safer for you to prearrange a taxi than to try to heil one from the street or airport. You might want to ask the program if they have any prearranged transportation or discounts with specific taxi companies.
Again, if you get into their program the parking situation won't be bad. Its terrible for guests for interview. Reason why is they got parking for the employees (you're not one), patients (you're not one) & visitors of the patients (you're not one). They don't have parking places for people coming in for an interview (or at least when I interviewed). If you bring your car, you might actually be better of lying & claiming you're a visitor of a patient. I chose to be honest and I kept getting turfed off to the next garage (there were at least 4 of them-the hospital's huge) who refused to let me park.
The situation may also be more organized for you than it was for me. A psyche residency usually considers dozens, possibly hundreds of candidates. A forensics fellowship may consider as many as a handful to maybe around 20-30 tops. Their general psyche residency interview process I figure is more organized. Several forensics fellowships I applied to seemed to be haphazardly organized.
Despite my rant, I actually was quite impressed with hospital facilites, and the people I did interview with were very nice. If you're into the hippy, nature, college student scene, you'll probably love the place. It wasn't my first choice place, but I could see myself liking it there very much. A buddy of mine graduated from their forensics program & had very good things to say about it.
