How to Prepare for a Professor Phone Call (2026)

Most PhD interview guides jump straight to the formal, scheduled interview, panel questions, multi-day visits, a fixed slot on a department calendar. They skip the conversation that often happens first: a professor reads your cold email, likes it, and replies asking for a quick call instead of just answering by email. That call is genuinely different from a formal interview, less structured, often shorter notice, sometimes arranged within days of your original outreach, and almost nothing online tells you how to prepare for it specifically.

Read the signal correctly first

A professor proposing a call instead of replying by email is doing something that costs them real time out of a busy schedule. They don't do that for every email that lands in their inbox, most cold emails that don't fit get a short decline or no reply at all. If you've reached this stage, the professor already sees enough in your background and your email to want to hear more directly. Treat the call as a genuine evaluation conversation, not a formality, and prepare accordingly rather than assuming it's just a friendly chat with no real weight.

What the call is actually for

Two things happen at once on this call. The professor is assessing whether your background, communication style, and research interests hold up in a live conversation the way they read on paper. And you're assessing the same thing about them and the lab, whether the working relationship feels workable before you invest months into a full application or a formal interview process. Go in with real questions of your own, not just answers prepared for theirs.

Logistics: get the boring part right

None of this decides the outcome, but getting it wrong is a distraction you don't need. Confirm the time zone explicitly in your reply rather than assuming, a professor in Melbourne and an applicant in Lagos or Toronto are working across a gap that's easy to miscalculate. Pick a quiet space with a stable connection, close other tabs and notifications, and have a notepad or document open to jot down anything specific they mention, a paper, a collaborator's name, a funding detail, so you're not relying on memory afterward. If it's a video call, treat it the same way you'd treat any other virtual interview, see our guide on what to wear and how to set up your background for a professional-looking call.

Prepare a short, spoken version of your background

You'll almost certainly be asked some version of "tell me about yourself" or "walk me through your background," and reading it off a script sounds exactly like reading off a script. Practice saying it out loud, not just writing it, until it comes out naturally in conversation. The useful structure is short: your academic path in a sentence or two, the specific experience that led you to this research area, and why this particular professor's work, not research in general, is what brought you to reach out. Ninety seconds is close to the right length, long enough to be substantive, short enough that it doesn't turn into a monologue before the professor gets to ask anything.

Re-read the paper you referenced in your original email

If your cold email mentioned a specific recent paper, and it should have, expect the professor to follow up on it directly. Re-read it the day before the call, not just skim your own summary of it from weeks earlier. Be ready to explain what specifically interested you and, ideally, a genuine question or extension you've thought about, not just praise for the work. If you're not confident you can hold a real conversation about a paper on short notice, our guide to reading a professor's paper well enough to reference it specifically covers the fast version built for exactly this situation.

Have your own questions ready, not as an afterthought

A call that's entirely you answering their questions and offering nothing back reads as passive, and misses a real chance to learn whether this lab is actually right for you. A few worth having ready: what does a typical week look like for a student in the lab right now, is there an open project you'd likely start on or would you be developing your own direction, and what's the current funding situation for a student starting in the relevant intake. That last one is worth asking carefully rather than avoiding, see our full breakdown of how to raise funding without it feeling awkward for how to frame it on a first call specifically, where it can feel earlier than expected to ask.

Common questions that come up on this specific call

Expect some mix of: why this research area and why now, what your day-to-day availability and timeline look like (are you applying this cycle or the next one), whether you've applied or plan to apply to the formal program yet, and what draws you to this department or country specifically beyond the professor's own work. None of these need a rehearsed answer, but having thought through each one once beforehand keeps you from freezing on a question you genuinely hadn't considered.

If you don't know the answer to something

Say so plainly rather than guessing or going quiet. "I haven't looked into that yet, but I'd want to find out" is a normal, honest answer to a logistics question you genuinely haven't researched, and it lands far better than an invented answer that turns out to be wrong once the professor checks. The call is testing whether you're someone worth investing supervision time in over several years, not whether you have every detail memorized on day one.

If the call is scheduled on short notice

Sometimes a professor replies the same day proposing a call within 24 hours, which doesn't leave much room for deep preparation. If that happens, focus your limited time on the two things that matter most: re-reading the specific paper you referenced in your email, and re-reading your own email so you remember exactly what you said and can speak to it consistently. Everything else, polished questions, a rehearsed self-introduction, is worth doing if you have the time, but those two are the ones that actually prevent an awkward moment where the professor references something you wrote and you've forgotten the details.

Common mistakes on this specific call

A few patterns come up often enough to name directly. Talking for the entire call without leaving room for the professor to ask their own questions, which happens when nerves push someone into over-explaining. Criticizing your current supervisor, program, or workplace at length, even honestly, reads worse than staying neutral and focusing on what draws you forward rather than what you're running from. And treating the call as already decided, talking about "when I join the lab" rather than "if this turns out to be a good fit," which can come across as presumptuous before either side has actually agreed to anything.

How formality expectations shift by country

A first call with a professor in the US or Canada often runs more conversational and informal than the same stage in the UK, Germany, or parts of East Asia, where a first conversation can carry more of the tone of a formal interview even when it's framed as "just a chat." This isn't a hard rule, individual professors vary widely regardless of country, but it's worth calibrating your own formality slightly upward if you're unsure, since a call that turns out more formal than you prepared for is a harder recovery than the reverse. If you're applying across multiple countries in parallel, our country-specific guides for the UK, Germany, and the USA cover how funding and supervision norms differ enough to change what's worth asking on this call.

What to do in the minutes right after the call

Write down what was said while it's fresh, specific project ideas, names the professor mentioned, anything about funding or timeline, even a rough sense of how the conversation felt. If you're talking to several professors in parallel, and most serious applicants are, these details blur together within days. A short note after each call becomes the record you actually rely on when deciding where to focus later, not a polished memory that's already mixing details from a different conversation. A brief thank-you email within a day or two is a reasonable next step, our guide on following up after a PhD interview covers timing and tone if you're unsure whether a short call like this warrants one.

Getting to this call in the first place

This entire guide only matters once a professor has actually replied to your first email, which is the part most applicants get stuck on long before any call happens. GradScoutFunding finds professors filtered by field and country, confirms they're actively publishing, and drafts a genuinely specific first email grounded in a real recent paper for you to review and send yourself.
