I applied in-person. I interviewed at Amazon
Interview
I was recruited by an outside company. I worked as a temporary hire for 5 months then was offered to possibly “flip” aka interview for my “blue badge” aka a permanent employment opportunity. I accepted, and had one interview with three individuals who I already knew and was well acquainted with. It was in person. You go through a portion of technical questions and leadership principles that AWS looks for. Here are some of the questions, answers, and the formatting that they like to see.

- 1. A server’s primary parts are its MOBO, CPU, memory, PSU, controller, backplane, cables for sata, power, and scsii, as well as its disks, heat sinks, fans, riser cards, controller battery, and DIMM. The Basic Input Output System (BIOS) initializes and tests the hardware components of the system. Loads a boot loader or an OS. 3. The different RAID levels are as follows: 0-Striping-No Redundancy-1 disk 1-Mirrored, Redundancy-need at least two disks 5-Striping with parity, need at least three disks 10-Combo of striping and mirrors 4 disks 4. Application, Presentation, Session, Transport, Network, Data Link, Physical 5 are the layers of the OSI model. On a Linux host, error messages can be found in Var/log/messages and dmesg 6. There are a number of ways to determine how much memory a host has, including the free command, proc/meminfo, and the top 7 methods listed below If you have a server that displays a failed DIMM, please describe the steps you would take to fix the issue. Reseat DIMMs Run Mem Test Use memory tester if one is available If Mem Test does not identify the failed DIMM, then take out all the memory except for the first stick and boot it up with each stick one at a time to ensure all sticks were functioning properly. To rule out bad mother board slots and failed DIMMs, add the memory back one stick at a time. Linux has several run levels, including 0-halt, 1-user, 2-user with networking, 3-user defined, 5-user with GUI, 6-Reboot, and 9-user. What are some Linux commands that you know? 10. Single mode is one directional, while multi mode does both. Single mode is more expensive than multi mode. Single has a faster speed and covers a greater distance. The system goes through POST Power is initialized, the BIOS is initialized, POST tests internal and external components, disks and RAID systems are initialized, the system determines the primary boot device, reads the device’s Master Boot Record, the boot loader begins, Grub or LILO is loaded, the boot loader determines and decompresses the default kernel image, the kernel loads modules for all the hardware and initializes it, and the kernel begins the init process. local, TTY sessions, and the system’s login screen 13 What distinguishes TCP from UDP? TCP has a handshake. Cares about packet loss. TCP is more reliable than UDP UDP- hard and fast. Does not care if there is package loss. 15. What distinguishes GRUB from LILO, which has a cli interface and supports network booting? LILO cannot start over a network, but GRUB allows for the booting of multiple operating systems simultaneously 16 Some messages may be visible during post, var/log/messages, dmessg 17; how would you check for errors during boot? Describe the steps you would take to fix a server that won’t turn on: check the power button, see if the host is powered on, check to see if the motherboard lights are active, and see if the RPDU breaker hasn’t tripped Verify that power cables are connected Use a different power source if one is available Open the case and make sure that all internal power cabling is connected correctly and that other internal components are seated properly Replace the power supply What distinguishes a router from a switch from a hub? Hubs are the least intelligent of the three and will forward to anything connected to them. Layer 2 switches are the cheapest of the three, remembering where devices are connected and ideally preventing collisions. Routers are the most expensive of the three, use routing tables, and are the smartest of the three. What steps would you take to troubleshoot and repair a host if you had a server that had lost all of its data drives? Check to see if the host can be shut down with the owner Reboot the host, and see if the drives come back online Reseat the drives, reseat the controller, and double-check that the cabling is connected properly Check the controller to see if raid is still present Replace controller Replace back plane Replace disk cabling Customer Obsession, Bias for Action S:

Anyone here with experience working in a DC or for the IT side of AWS who could offer some advice? I currently understand hardware troubleshooting, some beginnerish network troubleshooting, and basic linux command line functionality. Looking for more details about the work environment, the workload, and how difficult it is Last but not least, what is the nature of the interview? I was told it will last only 30 minutes, but I’ve never interviewed for a IT position. For policies and procedures, whats the extent of being able to improve upon them? Also, how necessary is it to know Amazon’s leadership LPs?
Finding a new job can be so difficult that it becomes a job in and of itself. A skilled worker supporting an organization’s data center is a data center technician. Many organizations are looking for candidates for various roles as data center technicians. Job opportunities are present everywhere for this position. Job duties for a data center technician may include responding to inquiries and concerns from a variety of sources and providing accurate information to business executives on the operations of a data center and its optimization procedures. Data centers frequently have their own designated staff and operating procedures for maintaining particular or specific operations. Interview questions were specifically developed by Wisdomjobs for job seekers. To prepare for the interview, check out our page with Data Center Technician interview questions and answers.
For instance, “I would first see if the cooling system’s dashboard displayed any error messages.” If not, I would then verify the functionality of the temperature sensors. If they weren’t, I would replace them. If they were, I would check the motherboard of the cooling unit to make sure it wasn’t harmed. If it isn’t, I would restart the cooling system. ”.
Example: “I’d suggest upgrading our servers to more capable models with increased processing and storage capacity.” Additionally, I recommend adding more servers to the current setup so that we can scale up as necessary. Utilizing a virtualization platform, which enables us to run multiple operating systems on one server, is another tactic I would use. This lessens the amount of physical servers we require while still enabling us to grow as needed. ”.
For instance, “The server room, backup power supply, cooling system, UPS unit, network equipment, and storage devices are the main components of a data center. The servers, which house data for customers or businesses, are all housed in the server room. Backup power supplies provide energy in case there’s an outage. A UPS unit provides short-term power when there’s an outage. Network equipment includes routers, switches and firewalls. Storage devices include hard drives, flash drives and optical drives. ”.
Example: “I believe that working with sensitive data is the biggest challenge that data center technicians face.” This necessitates that we exercise greater caution when handling tools and paperwork, which could cause a delay in our workflow. But I’ve discovered that if I’m organized and follow the right procedures, I can still finish my tasks quickly while protecting company information. ”.
The answer to this query will allow the interviewer to gauge your level of familiarity with data center management software. If you’ve used this kind of software in the past, describe the program you used and how you used it to carry out your tasks. If you have no prior knowledge of data center management software, you can state that you are open to learning new ones if necessary.
