Cognizant interview questions

Keeps calling and rescheduled the interview for more than 3 times . At the end, interviewer did not turn up. Is a very uncomfortable and lousy experience. Will not consider for this kind of company.

only one interview round with simple coding questions in sql, python and questions about oops concepts, dbms concepts, all on a very basic level. i was asked to code on my laptop to show the code which would be checked by the interviewer, but execution was not required.
