Ashtech Infotech interview questions

One of the worst process, first they will make you wait for 3 to 4 hours no proper management at all, I had gone for the sales executive profile of ashtech but they offered me the job profile of another company. Like I don't understand why to waste the time of people when you yourself are not sure for what position you want employees to work.

15 MCQ questions and 2 coding questions were asked. In MCQ, questions were from Aptitude, DS, CN, and DBMS. Coding 1: Count the distinct pairs with a difference equal to k. Coding 2: I don’t remember exactly this.
