You may think that certain things are cliche to say in an interview. But say them anyway! You can substantially upgrade the impression you make by hitting on these common points.

The top three OBVIOUS things to say in an interview...

#1 - "I want this job"...
I can't believe I actually have to remind people to say this. It is such a boost to an employer when you state your true interest in the position. Some candidates feel that this should be assumed and that by virtue of the fact that you have driven your car to their office and are sitting in front of them in a suit that they should know this. Don't make them guess. Tell them that you are interested in this position and why. In fact, try to do this right at the beginning of the interview to set the tone, show them you did your homework and do indeed know what the position is. This will kick things off on a really positive note with the Hiring Manager.

#2 - "I believe I am well qualified for this"...
Don't let your resume do the talking for you or assume because you have had a good discussion about the position and your skills that this point gets made on its own. The best time to say this is towards the end of the interview. It creates a nice opportunity for a summary statement of your strengths and exudes the appropriate level of confidence. Also, always be detailed and specific about why you do feel you are qualified.

#3 - "I really enjoyed meeting with you"...
This is an absolute no-brainer and a necessity. Always express that you enjoyed speaking with them at the end of the meeting. It's flattering to the Manager and shows your good manners. If you can speak to any specific elements of why it was so enjoyable, mention this. This could be something you learned or thought was interesting and cool.

These may seem like silly things to have to suggest, but these three statements when made honestly and with actual specifics can make a big difference.
