major bugs means:
1.If we want to access any page then we have to enter
correct URL in that type server was not founding that
particular page dispalying error like "server not found".

2.Functionlality is not effecting correctly

3.Showstopers---like application is not responding correctly.
for ex:we have to enter 30-02-2007 date(invalid date)
in that application was hanging it's not working forther step.

there are lot of bugs we can find while testing
those are
i)user interface bugs,
ii)calculation bugs,
iii)database related bugs and
iv)error messages

We will be finding lot of major bugs while testing.
If we tell our major bugs then you will not able to 
understand that bug becoz you dont have knowledge on the 
domain which we are working. right..?

My suggestion here is:

you would be putting some projects in your resume. so 
assume from your project and analyse and here what ever you 
analyse and you can create your own bug list.
I will give an example.

you know very well about the Gmail. right.

1. As per client when you login to the Gmail then INBOX 
page should open. but when you loging in to Gmail you are 
able to see DRAFTS page. Then this is a bug.

2. As per client when you compose a mail and given all the 
inputs like valid mail id , subject and description then 
click on SEND BUTTON . the mail should be sent successfully 
but here when you click on SEND button then the mail is not 
sent successful instead it's getting saved and stored in 
DRAFTS folder. This is an another bug.

3. In preference settings you have option of  changing the 
password but when you tried to change your password then 
that functionality is not working as expected. This is an 
another bug.

so in this way you have to analyze the things and you 
should need to have creativity. what ever you say it is bug 
from your project then the interviewer will hear you 
because you  must be not knowing the domain. right.
so all ways think positive and attend the interviews all 
the best.
