    I have been working for T&T Consulting, Inc. for a few years now and I have to say that they are the best company I have worked for in all of my years as a contractor for the government. They really show their appreciation to their employees and encourage them to move up in the company. If you are looking for a great company to work for, look no further. They have positions working in an office and remotely at home so it is a win-win situation for whatever your needs may be. I love working for T&T Consulting, Inc.

    Corporate Support Interview

    Anonymous Employee in Falls Church, VA
    Accepted Offer
    Positive Experience
    Average Interview


    I applied through a recruiter. I interviewed at T and T Consulting Services (Falls Church, VA).


    I had two interviews, the first was an initial phone screen with the Contracts Manager, and the second was an in-person, round table style interview at the corporate office with the CEO, COO, and CIO. They were all very welcoming and professional.

    I liked that they took the time to explain their needs for the position first, before asking me about my experience. I found this additional context to be extremely helpful in framing my responses. I feel like in other interviews, it's like shooting in the dark to try to figure out if your answer is what the interviewer is looking for.

    I also really liked the fact that I got to speak with most of the leadership team all at once. I thought it would be really nerve-racking going in, but it was actually really nice to see the dynamics between the company's leadership team, and they made me feel really at ease throughout the interview.
