It depends on what they are calling u for. If its 4 DSA/marketing,my bros run 4 ur life bcos d salary was just reduced 4rm 25k to 20k but if u're determined & hv connections,u MAY be able to do it.if not,RUN 4 UR LIFE.
As 4 d test,d questions are mainly based on diagrams. Few questions consist of simple maths(series & sequence) & verbal reasonin.
My advice is dat u give it a try like i did but later ran away. Who knows u may love the job. Wish u success in ur test
