What Makes a Good Résumé

Last updated: August 4, 2026

Most résumés list what someone was responsible for. Good ones show what changed because that person was there. That is nearly the whole difference, and it explains why the hard part is not the writing. It is remembering what actually happened.

Why they all read the same

Open ten résumés for the same role and most of them describe the same job. Responsible for managing client relationships. Worked closely with cross-functional teams. Involved in the migration.

None of that is untrue. It is just not about you. Everyone who held that title was responsible for those things, including the people who did them badly. A line that would be equally accurate on a colleague's résumé is not telling anyone why they should pick yours.

The fix is not better adjectives. Adding "successfully" to a duty does not turn it into an achievement. What separates the two is evidence: something that happened, that would not have happened the same way without you, described plainly enough that someone can picture it.

What goes on it

Strip a good bullet back and there are three things in it.

Most weak bullets have the first one and stop. Most overwritten bullets have the second one with nothing underneath it, which is worse, because an unbacked number invites the one interview question you cannot answer.

The line that gets read

It is easier to see the difference than to describe it. These use invented client names, but the shape is the point.

Duty Responsible for the content management system migration.

Result Migrated Contoso's content management system end to end, cutting page load time 42% and lifting checkout conversion 8%.

Duty Worked on improving the mobile app experience.

Result Shipped offline mode and push notifications for Northwind's mobile app, dropping the crash rate to 0.2% and cutting support tickets 30%.

Duty Managed the customer onboarding process.

Result Rebuilt onboarding for 35 new clients, cutting the back and forth before kickoff and giving account managers one handover checklist to work from.

Duty Involved in team mentoring and process improvement.

Result Coached two engineers to promotion and halved mid-sprint scope changes by tightening how work was planned.

Notice that the strong versions are not longer by much. They are the same length doing more work. And notice that the last two have no percentage in them at all. They are still specific, because something is measurably different afterwards.

What to cut

Space on a résumé is the scarcest thing you own. Every line that is not earning its place is pushing a line that would.

The part nobody warns you about

Almost every article about résumés assumes you know what you did. That is the assumption that breaks.

You finished the migration in March. You are writing the résumé in November, on a Sunday night, because a posting closes on Friday. The work is eight months behind you. You remember that it went well. You do not remember that page load dropped 42%, because you saw that number once, in a dashboard, on the week it shipped.

So the bullet becomes "Responsible for the content management system migration." Not because you don't know better, but because the specific thing is gone and the generic thing is all that's left.

This is why the advice to "quantify your achievements" is so annoying. It is correct and it arrives eight months too late. Quantifying is not a writing skill. It is a record keeping problem wearing a writing skill's clothes.

The people who write good résumés quickly are almost never better writers. They kept notes.

That's what Panda's Recap is

It is a board where you run your work: tasks, timers, clients, projects. Track your work as you go, and the record builds itself as a by-product of doing the job, rather than as a separate document you have to remember to maintain.

When a role comes up, that record becomes a résumé. Real projects, real hours, and the results you noted at the time, instead of whatever you can reconstruct on a Sunday. You decide what belongs on it: internal work can be marked to stay in your own record and out of the résumé, without deleting anything.

A résumé generated by Panda's Recap from tracked work: name, job title and contact line, a summary paragraph, skills grouped by platform, engineering practice and delivery, then an experience section where each bullet names the client and the result.

A generated résumé. The names and companies here are invented; the structure is what the tracked work produces.

The board, the timers and the reports are free, with no account needed. Generating the résumé is part of Pro.

Common questions

How long should a résumé be?

One page is usually enough early on. Two is reasonable once the extra experience is relevant and substantial. Years are a poor dividing line: twelve repetitive ones can fit on a page, while seven varied ones might not. The real test is whether every line helps make the case for you. A two page résumé of real results beats a one page résumé of job descriptions.

What if my work doesn't produce numbers?

Plenty of good work doesn't. Use scale, frequency or the change in state instead. How many people, how often, what it replaced, what stopped going wrong. "Ran the on-call rotation for a team of nine" is concrete without being a metric.

Do I need a different résumé for every job?

For any application you care about, yes, tailor it. But tailor from something. Keep one honest master record of what you actually did, then build each version by bringing the most relevant work forward. The version changes; the record it comes from does not. Rewriting your history from memory every time is how details get invented.

Should internal projects go on my résumé?

Only if the outcome makes sense to someone outside the company. Internal tooling with a codename means nothing to a recruiter. Either translate it into what it achieved or leave it off.

Is it a bad idea to have AI write my résumé?

It depends entirely on what it is writing from. Asked to invent a résumé, a model produces confident fiction that falls apart in an interview. Given a real record of what you did, it is doing the part you are worst at, which is turning notes into sentences. Read every line before you send it either way.
