Getting someone to agree to a short call is a good start, but the call still needs a little preparation. If you show up with vague questions and no clear purpose, the conversation may be pleasant but not very useful.
A good coffee chat is simple: respect the person's time, ask thoughtful questions, learn something real about the team, and close with a sensible next step. Sometimes that next step is a referral. Sometimes it is another person to talk to. Sometimes it is just better information. All three can help your search.
An informational interview has three practical purposes.
First, you want to understand the team better than a job description can tell you. Second, you want the other person to see that you are serious and prepared. Third, if there is a real fit, you may want to ask about the best way to be considered.
Do not treat the call as a hidden way to get a referral. People can feel that. At the same time, do not pretend there is no job-search purpose at all. The honest middle is best: you are exploring the company, you value their perspective, and you would like guidance on the right next step if the conversation goes well.
Preparation is what makes the call useful. Ten minutes of research before the conversation helps you ask better questions and avoid spending the call on things you could have found yourself.
Here is the full arc of an informational interview, from prep to next step.
The middle of the call is where you learn about the team, but the two ends carry most of the value: arriving prepared earns the person's attention, and closing with a clear next step turns a pleasant chat into progress on your search.
Read the person's LinkedIn profile, skim the company's engineering blog if they have one, and review the role or team you are interested in. Look for two or three specific things to ask about, such as a project their team shipped, a technology they use, or how the team is structured.
Test your audio, have your questions written down, and keep your resume nearby in case they ask about your background. You do not need to sound rehearsed, but you should be ready.
Thank them for making time and confirm the length of the call. A simple opening works: "Thanks for taking the time. I know we planned for 15 minutes, so I'll be mindful of that."
Start with specific questions that show you did basic research. Then listen. This should feel like a conversation, not an interview script.
They may ask what you are working on or what kind of role you want. Have a two-sentence answer ready so they understand your background without getting a long career history.
In the last couple of minutes, ask a next-step question that fits the conversation. You might ask whether the team is hiring, who else you should speak with, or whether they would be comfortable referring you for a specific role.
Send a short note within a day. Mention one specific thing from the conversation and thank them for their time. If they offered to refer you, include the role link, your resume, and a short summary.
Good questions help you understand the role and show that you came prepared. Vague questions make the other person do too much work.
Five questions worth asking:
Five questions that waste the call:
The last two minutes matter. Do not let the call end with only "this was great, thanks." Ask for a specific next step that matches how the conversation went.
If the call went well and the team is hiring, ask directly but politely:
If the team is not hiring, or you are not sure a referral ask fits, choose a softer next step:
Both options keep the door open without pushing too hard.
Then send a thank-you within a day and make it specific.

Why this works: It references a specific moment from the call, confirms the next step, and gives them what they need if they offered to refer you. It is specific without being pushy.
A coffee chat can end pleasant and still leave you with nothing useful, usually because of one of these six errors.
