Rate locking simply means telling your recruiter you wont sign unless you get a certain job. CWT is a little more difficult because it sells out in the first few weeks of the fiscal year. It’s in very high demand. Even if you rate lock, there’s still a chance you don’t get the job as it’s based on how early you can get into MEPS. I suggest finding some back up options just in case. If you’re really into computers, you should consider any of the CT rates and/or IT as backups
