I’ve been independent/contracting/freelance for som eyears now. Typical turn around in contracts is anything from “start tomorrow” to a max of about two to three weeks. As a general BA you will be competing against equally capable people who are ready to start. Most consultants who go into contracting do so after being made redundant or in good times when it is easy to take the plunge and hope for the best.The question of notice period is entirely dependent on circumstances. If you’re a bit rubbish and on the bench, then I’m sure your firm will let you go the same day. If you’re currently billable and difficult to replace (or your release would mean you not being replaced by another billable colleague), then I can imagine them holding you to your notice period.A warning - have you actually been to any interviews yet? Clients (and especially agencies) are very suspicious of permie employees who come to contract interviews. Comes across as a permie that’s heard contracting pays well, rather then someone committed to providing independent consulting services. Agencies hate it because theirs is a very high drop out rate from offer to acceptance.
