Hey Animesh.
100 percent placement is a myth as every Institute assure of it , students tend to take admission
Recruitment officer from various companies look at the following aspect to select you.
1.) English profecient Student.
2.) Grades.
3.) Knowledge about the relevant field.
4.) Personality.
5.) Willingness to work ethically.
If you excel at these 5 things than assured placement is guaranteed.
Don't fall for 100 percent placement policies.
Hope this helps.
