Well, (sentence)

You use "well" to change the topic or the tone of a conversation:

A: How are your classes going?

B: Not too well, to be honest. Calculus is kicking my butt.

A: Well, hang in there.

B: Yeah, I'll try. Hey, have you talked to Priscilla lately?

You can also use "well" to signal the end of a conversation. For example, you might say this after talking to someone who's just returned to work from maternity leave:

Well, it's nice to have you back.

a great fit for (a job)

This phrase is often used when talking about open positions and job applicants. If you think that a person is "a great fit" for a job, it means that you think they can do the job well.

You might get a question like this in a job interview or on an application form:

Why would you be a good fit for this position?

If the company rejects you, they might write this in an e-mail to you:

Unfortunately, we don't feel that you'd be a good fit at this time.

You can also talk about it the other way: a job can be a "great fit" for a person:

I think this job would be a great fit for you.

I was a middle school teacher for a few years, but it wasn't really a good fit for me.

(someone's) team

In business, people often call the group that they work with (their company or department) a "team". For example, if a company wants to hire people to work for them, they'll put a link on their website which says:

Join our team.

Small companies also advertise the people that work there in a section on their website titled "Our Team".

You can name other departments or groups in your company by one of their members:

What's Becky's team working on these days?

And if you want to praise the people who work for you, you can say this:

We've got a fantastic team here.
