Amazon Web Services - Herndon VA
Applied on the careers website. Got a call after 4 weeks from the recruiter asking me for a time to have my first telephonic interview.
First interview was for 1 hour, in which, I was asked all technical questions. Questions included,
1. OSI layer model - Be prepared to explain each layer
2. TCP vs UDP,
3. Subnetting, subnet mask ( Gave an IP and asked me to subnet it )
4. PowerShell scripting questions ( basic command lets, what command is used to read the contents from a file, can we use a where clause inside a where clause )
5. NTFS vs FAT 32
6. Explain GPO
7. Fully Explain DHCP, DNS, DNS records - Very Important
8. What happens when we type amazon.com in a web browser.
6. At the end, I was given an opportunity to ask question if I had any.
Next day, I received a call from the HR saying they would want to have a telephonic second interview
Second interview was also for 1 hour, I was asked technical and situation questions
1. Database basics ( Delete vs Truncate, Primary Key vs Unique key vs Foreign Key )
2. Port numbers ( TCP, UDP, RDP, SQL server default port etc )
3. What are all the registry's present in windows registry
4. Whats sysprep
5. What are the different logs regsistered in Event viewer
6. Explain a situation where you worked on something which you are proud of
7.How do you deal with slow working peers
2 days later, I was asked to come for an onsite interview. All expenses paid for. I was asked to sign a non disclosure so I cannot give the exact questions. The interview consisted of four 45 min interviews. First two were fully technical, two were situation based. You have to be strong in Networking skills and scripting skills. Situation based questions can be tricky so be prepared to answer them properly.
Interviewers are very kind and the process was cool. They do not try to grill you but want to know if your basics are strong.
