Engineer

You can pursue a mechanical design course from CTTC for the same.

If your diploma course in engineering is recognised by the state council for technical education and AICTE and is considered equivalent to a polytechnic diploma then I don't think there is any problem.You are eligible for junior engineer's post. All the best.

EEE graduates can seek jobs in Electrical & Electronics Manufacturing companies, Electrical Generation & Distribution firms, R&D firms, IT companies, Operations & Maintenance roles in manufacturing & Services companies, acedmics etc. EEE graduates are eligible for Junior Engineer role where electrical diploma holders are eligible.

You don't have to have pre knowledge to start learning SAP
