It's a. Whole day process.
First: machine test
Second: aptitude
Third: f2f technical
Fourth: f2f technical with leads or director
Fifth:HR
All rounds are steps rounds.
Machine test is very easy if you are a good developer.
Apptitude is easy but very short time available.
F2f technical is based on oops , core php, and current projects questions.
Fourth round is very logical and difficult to crack.
HR round very bad experience.
HR will not offer good package and negotiate like local market vendors.
