Three jobs in four years is within normal range in tech and increasingly elsewhere — it's unlikely to be held against you on its own. What raises concerns is a pattern of leaving before delivering anything, or a story that doesn't hang together.
**What employers are actually screening for:**
1. **Did you accomplish something in each role?** Eighteen months with a clear shipped outcome reads completely differently from eighteen months with nothing to point at. Duration matters less than delivery.
2. **Is there a coherent direction?** Three roles progressing toward a specialism reads as intentional. Three unrelated jumps in unrelated fields reads as drifting.
3. **Will you leave quickly again?** This is the underlying worry, and it's about their hiring cost, not a moral judgement.
**When it becomes a genuine concern**: several stints under a year, particularly consecutive ones; leaving mid-project repeatedly; or an explanation where every previous employer was somehow at fault. That last one is the biggest flag — a candidate who blames four consecutive managers is telling the interviewer something.
**How to frame it well:**
- Give each move a forward-looking reason: 'I moved because the second role offered ownership of the whole payments surface, which is what I wanted next.' Moving *toward* something is fine; a string of escapes isn't.
- Lead with achievements per role, so the reader sees output rather than dates.
- If a role was genuinely short and bad (a company that misrepresented the job, a restructure, a layoff), say so once, neutrally, without bitterness. 'The role was restructured four months in and the work I was hired for no longer existed' is a complete answer.
- If you're currently at a shorter stint and interviewing, be ready to explain why *this* move is different and what would make you stay.
**The other side of it**: changing jobs is frequently how people get significant pay increases, since internal raises tend to be capped by policy. That's a rational response to how compensation works, and many hiring managers understand it perfectly well because they've done it themselves.
**The practical advice going forward**: if you can, aim for at least one role of two-plus years with a substantial accomplishment in it. That single data point defuses the concern for the rest of your career, because it proves you can stay and build something. After that, the pattern reads as choosiness rather than instability.
