Ho sostenuto un colloquio presso Hexaware Technologies (Chennai)
Colloquio
Initially start was good and manpower firm for Hexaware followed up regularly to schedule the interview and rushing us to attend the second round as well. Don't know whether usually third round of interview will be there or not, they scheduled the interview by 12.30, postponed it to 3.30 then asked to join by 4.30 and then panel hasn't showed up from Hexaware. Almost, 2 to 3 weeks of time and hope has been waste.
It would be really appreciated if they communicate the things properly to the candidates who were expecting the updates from them
