I'm doing straight TC applications, unless the firm specifies that it recruits largely through its vac schemes. I haven't done a vac scheme but thus far, out of 4 applications, I've had 4 positive responses (two winter vac scheme interviews, one open day and a TC interview for January) so I don't see any point hanging around and waiting for summer vac schemes to roll around. I need the TC now! Also the magic circle firms and a number of silver circle/city firms interview and offer to non law candidates between now and April.
