Why would a top department hire a less experienced researcher for a tenure-track position? Suppose that a top-N department at a big research university (for very small N) has the choice between two candidates for a tenure-track position:


Candidate A: a bright young researcher just done writing her dissertation, and
Candidate B: a more seasoned veteran with a several years of successful teaching, advising, and grant writing her belt (though not already tenured).


In other words, suppose Candidate B has already demonstrated that, in addition to doing great research, she can successfully navigate other important aspects of the job.  Candidate A seems like a bigger gamble: perhaps she will succeed in these other roles... and perhaps not!  Assume that the department in question can essentially hire whomever it wants, with very little competition from other institutions.

Question: What incentive would such a department have for hiring A instead of B?

I ask this question, of course, because I am a young candidate about to interview for a job at a top department, and I know that I am competing with more seasoned candidates.  How do I make a compelling case, despite my relative lack of experience?  What are some potential pitfalls to look out for during an interview? (E.g., questions that might expose my relative naiveté?!)  Do top departments really hire freshly-minted PhDs for tenure-track positions?  Or are they just panning for gold?

Thanks!
Candidate A might have a research agenda (either based on her dissertation, or on her formulated research plan) that fits better with the research agendas of other people in the hiring department, or with strategic priorities of the department or even other departments at the university.
Candidate A might already have collaborated with members of the hiring department, maybe in writing grant proposals.
Candidate A might be cheaper, in terms of salary, lab space, funding or anything else the hiring department may need to cough up.
The hiring department may be afraid that the "superstar" candidate B has so many more attractive offers that she would not accept an offer at this department at all, so they would rather not expend the time to go through the entire process with her.
Candidate A might just have better contacts, because her Ph.D. advisor is big friends with the dean of the hiring department, or (less sinister) the dean has met candidate A at a conference and been very impressed with her presentation.


My advice: do a little research on the people and the priorities at your target department, and emphasize unobtrusively in your cover letter and research plan how you could collaborate and find synergies. And tap your network. Good luck!
