You've landed an interview for what seems like a great job. But how do you pick up on the subtle signs that a workplace could either be your version of a dream or a nightmare? Even if you think you might have found the perfect fit for you, here are some tips on how to find out what it might really be like on the job.

The interviewing process is often thought of primarily as an opportunity for employers to find their perfect candidate for an open position. However, the interview also offers job seekers a chance to do their own research and investigation as to whether this company has all the qualities and values they're seeking. Try these techniques:

Seek clues about company culture.
As you walk through the office, think about the way it feels. Are employees alert and friendly, or do they seem to droop at their desks? Do they greet you and one another in the hallway? Listen to the office and take note of the tone of worker conversations. This will tell you a lot about the culture and morale.

Interview early in the morning or late in the afternoon.
Notice when people arrive or when they leave. If all employees exit promptly at quitting time, it could mean an unhappy or under stimulated staff who is watching the clock too closely. If the office is full long after the end of the business day, it could indicate unrealistic deadlines and expectations.

Don't be afraid to ask questions.
If certain benefits are a high priority to you, don't be afraid to ask about them. You probably won't get all the information on the spot, but knowing the salary, vacation and general benefits overview is an important part of deciding if a job is right for you.

Watch the interviewer closely.
Pay attention to the kinds of questions your interviewer asks, and make sure they ask if you have any questions about the job or the company. If your interviewer is rude, interrupts or is unfriendly, consider if you would want to work with or for that person.

Check for cleanliness.
Do work spaces seem comfortable, well lit, and organized? Visit the restrooms to see if they are clean. A messy restroom with inadequate supplies could indicate lack of respect for the workplace and not enough attention to bigger details.

Ask why the previous employee left the position.
Did the last person who had this job leave in a screaming fit, or were they promoted? Finding out why the vacancy is there and seeing how the interviewer responds to the question may be the key to making your decision. If it is a newly created position, ask why it was not filled from within the company.

Evaluate.
Is this the best job for you? Sometimes, if your gut tells you something isn't right, it might be best to wait for a better opportunity.

Even though searching for a job can be trying, if something doesn't feel right, it is better in the long run to choose a job that you will be happy with, rather than find yourself knee-deep in regret and frustration in a job you don't love.
