If they sound as positive and happy at the end of the interview as the beginning (or more so) is a good sign. You can't see them, so you have to listen closely for their words and tone. They might even speak a little faster, or share more, when things are going well. Saying something positive and encouraging too helps. You might want to continue on though, keep looking, just in case. No harm continuing the search. Sometimes days make a difference, and you don't want to miss any other opportunities. Better to keep active and keep going, than sit around and have jitters and be nervous. You'd also sound better over the phone if they called you back, to avoid the risk of sounding desperate or unconfident.

If they didn't hang up on you then you didn't do too badly. Seriously though, after an interview don't worry about it. Just keep moving and interviewing and don't look back. Eventually a company will call you to give you an offer. Concentrate on doing well at the interview and don't worry about afterwards.

Having a good interview really doesn't matter a whole lot. Because you aren't being evaluated in a vacuum. You can have the greatest interview ever up to that point.... and it won't matter if the next person has a better one. You do your best, and hope for the best. But you continue to look for opportunities until you actually get a written offer that you like.

When you get called back for an in-house interview.

I know it can be hard to wait and see if they will offer you a job. But remember that you can't really judge how good a fit this is going to be for you from just an interview. You will find out several weeks into the job if you made the right decision to accept the job. No matter how well the interview went, no matter how well you liked the people, and no matter how interested you are about the job they told you about, the job can still turn into a dud. You take a risk whenever you take a new job. So try not to worry too much and enjoy the job that you have now. Good luck!

People try to read way too much into interviews, and they think that the interviewer is speaking to them in some type of code that -- if they decipher properly -- will tell them if they are being hired or not. It sounds like you had a good interview and might be a strong candidate. Don't count on being the only person with a good interview and strong skills.

If you were interviewing with the actual hiring manager as in the person you would be reporting to if you took the job, and that person says "I'm going to tell HR to setup a panel interview for you" or something to that effect, then that's a good sign it was a good phone interview.

There are none. I've had interviews where I thought to myself, "Man, I nailed it!" Didn't get the job.

I'm not sure if this goes for all industries, but for my industry I've found that the interviewer seems to be focused on being as stoic as possible. So for the most part it's hard to guage. I've had really bad phone interviews that have lead to offers. And I've gone into interviews feeling I killed it, and totally bombed. I've even intentionally tried to tank interviews and end up getting offers. You honestly just never know.
