But what if those jobs were startups, and your reason for leaving is their successive failure? As a scientific and software dev worker I've done small businesses (wonderful but little career advancement), academia (stimulating but unsustainable), and big corporate (very stable but soul destroying). Next I want to see what startups are all about.
Startups would seem to have the scope for stimulating work, rapid advancement/learning and without the corporate grind / layers of bureaucracy. The oft-cited risk is that 9 out of 10 of them will fail, often in a fairly disorderly fashion. Presumably this is a risk to those who value stability and not having to search for jobs too regularly.
But aren't we supposed to be searching for jobs and keeping our networks and LinkedIn profiles ready for that next opportunity all the time? If you're following this practice anyway and value the stimulation of a changing workload, why can't you just save up the 3 months of buffer salary and jump from one startup to the next as (with 90% probability) each one collapses?
If it is understood that startups are like this, is it also understood by hiring people that an employment history full of startups is going to contain a lot of hopping?
Otherwise how do people who prefer startup work sustain a credible-looking CV? They surely can't all be hitting on the lucky 10%.
