Yes! Go to all the interviews! You have nothing to lose, and an interview =/= a job. You can always say no if an offer comes of it that you're not interested in. An interview will give you practice interviewing (so you can be ace when you're in one that really counts), and will also give you more information with which to make a decision about which situation you like best.
Let us know how they go.
I hope your "three hits in a day after a long time of nothing" is a sign of things to come. Mr. MoF and I will both be throwing ourselves to Scrutiny for Employment in the next few weeks. It is the suck.
Re: subways...
I have only ever experienced the Paris Metro,the Washington DC Metro, and the Chicago L. I have a love-hate relationship with the Metro. The quality of the experience (if being whisked underground at high speeds with strangers can be considered an experience from which one can reasonably expect "quality" of any sort) seems to vary in accordance with the French administration. I liked it better under Mitterand, but even under Chirac it got the job done. I like that it's relatively easy and cheap to get from any point in the city to any other point. Panhandlers make it uncomfortable but not unbearable; occasionally they add a bit of color to the experience which makes for better stories later. The flourescent lighting and depressing decor of some cars can suck the soul right out of a person, but some of the newer trains are quite luxurious as public transport goes. The fact that the Parisians have taken the time to turn many of their stations into
works of art is pleasing. I'm sure other cities do this too but I saw none in DC or Chicago and as mentioned my experience with city trains is limited to those few cities; the Paris metro being the only system on which I'm certain I've seen almost every single stop.
I also like not having to deal with parking or navigating unfamiliar streets. I know my way around Paris quite well, via metro and foot. If I had to drive in Paris I'd be lost constantly and/or at risk of dying in some horrible traffic altercation (the French are not known for their driving skills, Le Mans Grand Prix notwithstanding). I like that I can go to a cafe and get totally ripped on wine, and then not have to worry about how to get home. As long as I get out at the right stop, and have a hotel within stumbling distance of the final station, I'm set.
I prefer trains to buses because there is always a train; every 90 seconds or so. With buses you're going on their schedule and if you miss it,
tant pis. And on a bus, if there's traffic, you're stuck. I think city buses are pure torture. Trains are an at times inconvenient convenience, but worth the negatives, IMO.
