Skills & Expertise required of I/O Psychologist

I was browsing through some of the jobs requirements of I/O (Industrial/Organizational) psychologists yesterday and found out to my horror that I LACK A LOT of the skills that's required.

This is what I gathered from the job requirements and some articles that I read a while back. Skills needed:
- Mastery of finance (dang!)
- Strategy (no idea o.O)
- Marketing (none of this)
- Operation (maybe a bit?)
- Knowledge of the customer (have a bit of this i think...)
- Knowledge of leading edge practices (i'm trying to keep up by reading...)
- Creating and managing change (part of a consultant job...)
- Various certification like SHL accreditation (a 1 day course can cost $1000+) and cert IV in assessment & marketplace training (expensive too!)
- Psychological assessment (thank goodness I'm learning this in my course!)
- Interviewing skills (had some of this...)

So yeah, looks like lots of work needs to be put in before I can become a good I/O psychologist.

After looking through all these, I think what I'll go for in my placements are 1) Administration of psychometric tests 2) Recruitment related, e.g. interviewing and 3) Dealing with clients. That should serve my purpose and let me have experience in these areas. Still need to think it through and finalise things before I decide and send out my cv.
