Telephonic round: (1 hour) 1)Mostly about the previous projects. 2)Some technical questions based on the projects. Telepresence rounds: 1st round: 1)Discussed about projects. 2)Five raliway stations A B C D E are there. The train goes only in forwarding direction. Given ticket costs between any two stations. All the ticket costs will be positive. How do you find the minimum cost of ticket between two stations.I gave recursive algorithm. Alternative improved solution is bottom approach, I wrote that algorithm later. 2nd round: 1)TCP/IP protocol layers. Give protocols for each layer. 2)Preamble bits. Purpose? 3)ARP protocol 4)When do switch broadcast the packets. 5)Difference between TCP and UDP. 6)How TCP connection establishment happens. 5)program to convert from little endian to big endian 6)what are the different areas present in address space of process. 7)Where does global variable, static variables, mallac memory, local variables gets allocated in this areas. 8)volatile variable. Its purpose. 3rd round: 1)virtual memory 2)kernel space vs user space 3)paging 4)segmentation 5)interrupt context vs process context 6)DMA. 7)How do you find whether machine is little endian or big endian. 8)About projects 4th round: 1)What are your strenths. 2)What are your weaknesses. 3)Why should we hire you? 4)Explained about their work and asked What technical knowledge you bring to team if we hire you? 5)Salary expectations. 6)Are you willing to relocate? HR process is very slow. HR intially said i cleared the tech interviews and they are interested to give offer and later no call from them about the offer. After making 3 to 4 calls to HR, they said about no offer. Eventhough Tech interviews are good, as the HR are not responsive, i had overall negative experience.
