How to handle the parts that only come up when you already work there: telling your manager, proving you can do the next job, and following up well.
By the end of this guide you'll know how to prepare for an interview with your own employer: what to do before you apply, what to say in the room, what to send afterwards and when, and which familiar-feeling habits cost internal candidates the job.
The short version is that being known is not the same as being chosen. You still have to make a case, and you have to make it to people who can check it.
Before
When you decide to apply
- Book a 30-minute meeting with your manager to say you're interested and why it fits your career goals (Indeed, undated). Do this when you submit the application, not after the interview is scheduled — your manager's support helps, and they usually know things about the role that the posting doesn't (4 Corner Resources, undated). Harvard Business Review (2013) puts it plainly: tell your boss before you interview.
- Read the internal posting side by side with your current job description for 45 minutes and mark every duty you have never personally owned. Those gaps are your interview; everything else is background.
- Find your employer's internal transfer policy in the handbook or HR portal. Minimum time in role, manager sign-off and notice periods to the releasing team all vary by employer, and in some organisations by country or by union agreement. Check before you build your hopes on a start date.
About two weeks out
- Write six to eight behavioural stories using STAR — Situation, Task, Action, Result (University of Kentucky Human Resources, undated; ORISE, undated). Behavioural questions ask for specific past examples in order to predict future performance (SHRM, undated), so pick examples with an outcome you can name.
- Time each story. A full STAR story should run two to three minutes (LinkedIn Talent Solutions, undated). If yours runs five, cut the setup, not the result.
- Include one story about a mistake at work — what happened, what you did, what changed afterwards (DeakinCo., undated). Prepare it in advance so you don't improvise a defence.
- Pull your own numbers out of the systems you already have access to: volumes handled, cycle times, error rates, budget you've signed off, people you've trained. Internal interviewers can check these, which is exactly why they're worth more than adjectives.
The week before
- Run one 45-minute mock interview out loud with a trusted colleague or friend, so you don't ramble under pressure (BetterUp, undated). Reading your notes silently does not count.
- Spend 30 minutes with someone who does the target job now, or a peer in that team. Ask what the first 90 days actually look like and what the last person found hardest.
- Draft a one-page plan for your first 30, 60 and 90 days in the role. Keep it to one page and bring it.
- Print copies of your cover letter, resume, any letters of recommendation and a list of accomplishments (Indeed, undated). Bring one set for yourself and a set for the panel.
The day before and the morning of
- Get a full night's sleep, and leave your phone in another room or on silent so it can't interrupt (Indeed, undated).
- Dress as you would for an external interview, not for a normal Tuesday at your desk (Indeed, undated).
- Block 30 minutes either side in your calendar. Internal interviews are often slotted into the working day because you're already on site (Indeed Hire, undated), which means you can be walking in from a meeting that overran if you don't protect the time.
- Re-read the posting one last time and pick the three duties you will make sure you've addressed before you leave the room.

Frequently asked questions
Do I have to tell my manager before I interview?
Tell them before you interview rather than after (Harvard Business Review, 2013). Many employers also require manager notification or sign-off as part of the internal application process, and that requirement varies by employer and sometimes by country or collective agreement — check the policy. Beyond the rules, the practical case is strong: your manager's support can help, and they often know things about the role and the hiring manager that the posting doesn't (4 Corner Resources, undated). A short meeting when you submit the application, framed around your interest and your career goals, is the usual way to do it (Indeed, undated).
How long should I wait to hear back?
Most candidates hear back within one to two weeks (Indeed, undated). If you were given a timeline, use it. If you weren't, wait at least five business days before following up (Indeed, undated), or five to ten business days (Zippia, undated), then send one message to the hiring manager or recruiter. Internal processes can move faster than external ones, partly because scheduling is easier when candidates are already on site during business hours (Indeed Hire, undated) — but approvals, budget sign-off and notice periods can stretch things out again, and that varies by employer.
Should I really dress up when everyone there knows what I usually wear?
Yes — treat the internal interview with the same seriousness, preparation and professional dress as an external one (Indeed, undated). Walking in dressed for a normal shift tells the panel you see this as a conversation rather than a competition. If the role is on a plant floor, a ward or a kitchen where formal dress would be odd, aim one clear step above your daily standard rather than a costume, and bring the printed materials regardless.
What do I do if I don't get it and I still have to work there on Monday?
Ask the hiring manager for a short debrief within two weeks and ask for two specific things to work on, not general impressions. Put those two things into your next development conversation with your own manager so there's a record. Decide separately, and not in the first week, whether the answer was about this role, this timing, or this employer — those lead to different next moves. Keep your thank-you note sent either way; the person who runs this process may run the next one.
