It depends. If you're an iOS developer in San Francisco, you'll be hearing from us pretty regularly. However, we only contact members with new matches at most once every ten days and take care not to flood our members with too many at once. This give us a chance to review feedback and ensure that we are only sending you high quality matches based on the data we have about you and what the employers really want. There's a good chance this could result in a win-win.
On the other hand, if you are living in a market or working in a job function where we don't have as many employers, it could take many months or longer to get your first match. Another factor is if we have lots of members who have similar skills, we will only be able to match the very most relevant members.
