I recently interviewed for a junior systems administrator position supporting a federal contract. The role requires a Secret clearance, and the posting described it as a contract position but did not explain the contract's duration. Since I had only encountered shorter-term contracts before, I asked whether the job was permanent. The hiring manager clarified that it was a five-year contract that would be recompeted during the fourth year. I immediately said that arrangement was fine and explained that I only wanted to make sure it was not a six-month position. Later, I asked about the benefits and ended by saying I was excited and eager to get started. The interview itself seemed to go well, but I noticed the hiring manager's expression change after my question. Did I make myself look careless or uninterested, or am I simply overthinking the interaction?

For future interviews, ask about the contract directly: “What is the current period of performance, and how far along is the contract?” Federal contracts are often several years long and may be recompeted without automatically ending the work. Employees are sometimes retained by the incoming contractor, although that is never guaranteed.
You probably did not ruin the interview. Asking about the contract length was reasonable because the posting did not explain the term clearly. The wording may have sounded awkward since the position was already identified as a contract role, but you corrected the misunderstanding immediately. Interviewers usually evaluate the entire conversation, not one imperfect sentence.
That helps. I was nervous because this would have been my first federal contracting role, so I think I started second-guessing every word after the interview.
It is good to ask about anything that could make the job unsuitable, including benefits and employment terms. That said, the strongest closing questions usually focus on the team and the work, such as what a typical day looks like, which systems you would support, how success is measured, and what challenges the new hire would face. Benefits and contract details can also be confirmed with HR if you move forward, but asking them is not automatically a deal breaker.
Try not to read too much into a facial expression. You have no way to know what the hiring manager was thinking, and candidates often assume they failed when the interview actually went fine. Keep applying elsewhere while you wait, and treat this as useful practice regardless of the outcome.
I have had interviews that felt mediocre turn into job offers, while interviews I thought were perfect went nowhere. You really cannot predict the result from the interviewer’s reactions.

That is much clearer than asking whether a contract position is permanent. I was treating federal contracting like the short-term contracts I had seen before.
