Hi everyone !!

Congratulations to all, who are shortlisted for BARC CS Interview. Interviews are starting from 1st December, and book your slots for interview as soon as possible. Now, in this short period I would like to share few things which you can pick and revise for interview process. 

  1. Read previous interview experiences.  My Interview Experience . 
  2. Revise GATE syllabus thoroughly once, you can use your GATE notes. Now focus will  be on assertion-reason rather solving numerical questions. Why threading when multiprocessing is already there ? How will you design a firewall to stop a set of IP addresses ? What is the need of pipelining ? What other kinds of Databases are available ? Can you list some compiler optimizations and why they are used ? Use mutex to make H2O in synchronization ? which algorithm will you prefer when people are submitting forms on BARC website and we need to sort them based on name ? How priority queues are implemented ? What is CPU clock speed and what factors affect CPU clock speed ? Write a program to find whether two rectangles are overlapping or not ?
  3. Pick 4-5 favorite subjects and do extra revision. I used GeeksforGeeks articles during my preparations. They are effective also they are written in a very practical and comparative aspect. Example :
  4. Try to retain basic pseudo codes in mind, like bakery algorithm, Peterson solution, congestion control alogrithm, Longest common subsequence etc. 
  5. Try to touch those topics also which you have ignored partially or completely during GATE, because they ask question on them also.Like, what is CISC architecture, Symmetric and asymmetric multiprocessing, What are inodes and how free space are managed, etc.


Feel free to reach me for doubts during preparation !!! or

All the best !!
