Technology kiyanne track ekata.
Virtusa job name has 2 parts :
1. Designation
2. Track
So for ex: it would be like this: Engineer - Technology (Designation - Track) and of course only guys in technology track can become tech leads;
Hierarchy will be
Associate Engineer - Technology
Engineer - Technology
Senior Engineer - Technology
Consultant - Technology (These are ones who generally plays tech lead role)
Senior Consultant - Technology (Definitely Tech leads)
Normally Engineer level eke kenk tech lead wenne ne (Maybe Senior software Engineers can). Virtusa eke Tech lead kiyanne role ekak but Mubasher/hsenid wage ekak gaththoth eka designation ekak.
So it depends on the company. but tech lead is a higher role where the lead becomes the BOSS of a team of software engineers.
