I haven't set foot in this forum in years but felt compelled to chime in given the overwhelming negativity directed at medical students regarding the future of our field. Call me naive, but I still think rad onc is one of the best, if not the best, medical specialties out there.
I'm in my first year in practice. I did not go to Harvard/MDACC/MSKCC. I graduated from a well-respected program and I sent my CV to ~15 places (mix of academic and PP) and received 5 hard job offers, all on the east coast. I'm not anything special. I worked hard in med school and residency and felt fortunate to have the choices I had. In the end, my wife and I chose a job that's not in a major city (I did have options in major east coast cities) - but we chose to move to place we've always wanted to live in, where we could have better QOL in a less stressful environment. At least that was the was the perception, and now 9 months in, taking this job was probably the best decision I've ever made. I love my job. I make >Terry Wall median starting salary, my patient load is very reasonable, my dept chair is awesome, my staff is great, I'm home most days ~5pm to see my kids. In short, I love what I do, and I am thankful everyday I went into rad onc.
Are there malignant departments/practices out there that prey on young grads? Yup. I specifically avoided such places in my job search, and turned down more "prestigious" positions as a result. Is the job market tight? Yeah, it is. If you're dead set on living in places with competitive markets like Boston and NYC, be prepared to be overworked/underpaid if you get a job offer in these places. I suspect this is not unique to rad onc though.
At the end of the day, this is such an awesome field - rewarding patient care, intellectually stimulating treatment planning, controlled hours, good compensation. Like I said, I'm not unique. My former co-residents all seem very happy as well - most of them had multiple competitive job offers too. There is considerable selection bias regarding who spends their time on SDN venting...
