TCS Programming, Data Structures, Networks and OS, Database and Testing, Project and Other Department Students Tech

Programming, Data Structures and project related Technical Interview Questions

• "Write a java code using try catch statements"
• "Explain about your project, implementations, front-end, back-end, technical details etc" BE extra through about the details of all your projects 
• "code to implement a link list in C". "write it using pointers"
• Some will ask you to write code from your projects(For some mechanical students theory behind functionality of the project)
• swap function without using temp variable
• Explain linked list concept /stack/queue/trees
• Explain different types of sorting 
• What is a null pointer, void point and a wild pointer 
• Explain the object oriented concepts in java(polymorphism,inheritance,encapsulation )
• Then the sizes for various data types in C and Java
• Program using thread/overriding/overloading in java.
•  Infix/postfix/prefix convertions
• Java database connectivity.
• what is a constructor?
• other programs like prime numbers, odd/even easy stuff basic programming

Networks and OS 

• OSI layers in network model and functions of each layer
• difference between TCP and UDP
• "there are 2 systems in 2 different networks will you use a switch or a router to connect them"
• What is the difference between switch, router , bridge
• In OS questions related to the fork() command
• Scheduling algorithms in OS
• What is a semaphore
• How many bits in an IP address
• Draw a rough sketch of an IP packet
• Layers of TCP/IP
• A few questions related to the linux file system
• Questions related to network address and host address
• How is windows 7 different from XP
• what is paging and questions related to that.
• process life cycle
• What is the ping command used for?

Database and Testing

• This was all really easy MySQL queries which included select statements using where condition etc, very easy queries. 
• Also some questions about normal forms, 1NF ,2NF, CNF.
• Black box and white Box testing differences
• Types of testing?
•  What is a test case?
• Software life cycle models(waterfall models etc)
• what is meta data?
• Why is testing important?

This section had the most easiest of all questions, just study all the basics.

Other Department Students Tech Panel
Yes there is programming but it is not that deep here are a few samples

• "explain about your project "(most frequent question asked to 78.9% students i got this information from)
• Then the interviewer asks what programming languages you know (most replied C), then he asks you to write a simple programming like prime numbers ,swap without temp etc. In some cases write any C program
• To some EEE students the interviewer has ask how the ceiling fan/generator etc  works
• 4 Mech students and 1 ECE student told me that the HR asked them their favorite subject and to explain about it
• "what is CAD(he had CAD in his resume)"
• Some questions related to data structures basics "what is stack" 

Overall Pragramming and OS concepts are not going to be asked much unless you say you know them.For example if you say you know java obviously he is going to ask a lot from it. Mostly others departments had HR questions only or HR/tech.Everyone i asked said it was nothing tuff.Make sure you know C programming , at least the basics.
