"This information is very important." Years != Experience ...but thanks for confirming the shallowness of the recruiting processes we've all experienced.
So you seriously don't believe that the difference between spending ~1 month or ~12 months or ~24 months at a company (all are possibilities, when a date range reads "2012-2013") isn't important information for a recruiter? This isn't strictly about experience; it's also about whether someone a company is going to invest time in is going to stick around for a while, or is going to hop around a lot. But regardless, ye…
At one company it took them 2 weeks to set-up my email, 3 months to decide on which project to work on and in about 6 months I was delivering something. So 6 months "experience" actually meant zero. I was ready to deliver from day 1 but...
At another company I had all the accounts created by the end of day 1, already working on bugs the second day. Some projects took 1 month in total. 6 months could mean 6 projects. The amount of skills accumulated in that time was way over the skills accumulated at the first company.
As you can see the time interval is useless. I think it's fairer if the recruiter simply rolls a dice.
