Optimum solutions is a body shop meaning they are HR outsourcing company. They don't manage any projects. They hire and fire on behalf of client. I heard its pretty shady. They recently landed in soup because they don't hire enough Singaporeans. They hire people from India, China, Malaysia and place them here in banks.

Anyways their business model is very simple. If a client needs 8 people they will hire 12. 4 will be on bench and 8 will be live. If any performance drops in the 8 they will fire him/her and then place the bencher there. Normally they go based 1 year contract which some seriously shady clauses like if you go find another job you need to back pay 3 months pays etc.

The main risk is it that they will severely limit your chances of landing a decent perm jobs.

Good luck!
