I'm practicing online tests for all types of strategt firms. Where can I get paid / unpaid tests which are at least as challenging and preferably harded than tests for BCG and strategy houses' SQL style tests.
Aside from SQL, what kind of tests are there for strategy houses. (I realise this is open ended so long answers welcome!)
Do any coaches specialise in preparing for SQL / online assessment tests or do sessions on this as a one / two off?
