Re: The process is the punishment
what you say rings true if you're apply for CE-something.
But almost universally any company that runs a dbs check on new employees for a "pleb" position will automatically reject any failing applicants.
Previous comment is correct in regards to the conviction preventing them getting a job for a big player again.
Most big players check no days, and if they're checking then they''ll not offer someone with a conviction the job. It really is that black and white.
It will restrict the person to jobs in places that don't check. they don't need a custodial sentence to affect their future job prospects.
If what was done was particularly offensive in nature, or endangered lives then fair enough. Prison, but most CMA cases are unauthorised access, pinching data, or pinching cash electronically.
Around a third of males might have a conviction, but there's an informal list of "things we care about" and "things we will ignore" living with each company, HR team and recruiter. I'd imagine a CMA conviction is firmly in the former list, for IT positions, but something related to driving, or being caught with drugs 15 years ago, or a drunk and disorderly for example, might be completely ignored. I'd imagine that quoted 33% includes cautions, which can be for practically anything.
It's case by case per job they will be applying for in the future.
