On more than one occasion I have been asked “how do I get a job in IT?” This question could easily be shrugged off and relegated to the canned answers pile; phrases I have personally uttered in the past include “go get some certifications then send out resumes” or “play with computers for a few years and then apply.” These answers really are a cop-out on my part so I’d like to take a few minutes to apply some serious thought to the query and offer my thoughts.
What People Will Expect of You
While most people would say that having a large breadth and depth of knowledge in computers is the primary requirement for being employed in IT, I would disagree with this. There are a handful of very critical attributes that you will find in any IT Rockstar:
- Good Problem Solving Skills
- Critical Thinking
- Strong work ethic
- Ability to handle “Burst Stress”
Problem Solving is possibly the most important attribute any good IT team member will have. Problem solving is the core of our vocation, when you think about it. IT is tasked with solving problems that the other employees aren’t able to handle. You’ll also find that in many workplaces, the IT guys are the ones helping to solve other complex problems in the enterprise because of the problem solving skillset they demonstrate. Critical Thinking is another important skill to have when talking about technical jobs. Oftentimes the problem I’m trying to solve does not have an easy-to-see solution (sometimes, the cause itself is not immediately apparent.)
Do you like working long hours for little praise or thanks? That’s pretty much working IT in a nutshell. Performing server maintenance usually needs to wait until after hours, which generally means you’ll be putting in a full 8 hours for that workday, then many more hours that night to do the after-hours downtimes. Couple this with “burst stress” and you’ve got a recipe for gray hair. Burst Stress is common in jobs like police work or firefighting, where you have long periods of low stress followed by short bursts of extremely high stress situations.
What do you want to do?
There are a handful of disciplines in IT, each with their separate purposes. What follows is a breakdown of the individual disciplines and what that type of work entails. Regardless of what path you choose, you’ll likely start in an IT Generalist role, and many people stay in that role their entire career. I myself genuinely enjoy being a generalist; it means that any given day I might be working on any number of problems that aren’t the same old issues over and over again.
IT Generalist — This is often the least respected but most useful role in IT. As a generalist, you are a Jack of All Trades. You’re expected to understand not only Desktop and Server Support, but also have a useable knowledge set in Telephony, Networking, Backup and Disaster Recovery, and Security. When you start your new IT career, you’ll usually start as a quasi-apprentice in a generalist role. Once you’ve “earned your stripes” in a few disciplines, you’ll be more educated and ready to move to a specialization, if that’s your pleasure.
Desktop Support — The Desktop Support team will generally be tasked with maintaining the software and equipment that other people in the company utilize to get their jobs done. This job is very demanding from a customer service perspective, as the person doing this job will oftentimes be assisting users who are already annoyed that their machines aren’t working the way they’d like! Skillset wise, Desktop engineers need to be highly fluent in whichever desktop operating system your company uses, as well as any applications the company makes use of. Generally speaking, you’re going to need to know Windows and Office like the back of your hand if you want to get a job like this in the majority of businesses.
Server Support/Systems — The Systems or “Server Support” team has similar requirements as Desktop Support when it comes to strong knowledge sets of operating systems and software. The jobs diverge when you look at the “back-of-the-house” operations that a Systems team is often assigned. Knowledge of datacenter operations (power distribution, hot row/cold row, rack positioning) is essential in this role if your organization has more than just a “closet in the back with a few servers.” Server Support is also usually in charge of all backend/utility systems in the organization, including directory authentication, mail and groupware, and administrating backups.
Networking — This group focuses mostly on interconnecting sites and equipment together. To get into this group, you better be prepared to prove you know the OSI model like the back of your hand. This is a tough group to coast in; TCP/IP can be fickle under wavering hands. Usually, a particular company will standardize on one vendor for their equipment, and you’ll be expected to know the operating system for that particular vendor. If you’re looking to get into the networking team at a new company, you should likely know Cisco and Juniper OS’s (Cisco IOS/ASA-OS, JunOS, etc.) Even if the company does not use either of these major brands, having knowledge of how other platforms operate can assist you in doing the job. Networking also is susceptible to the above mentioned “Burst Stress”, since if a site-to-site link is down, it’s possible that hundreds of people are sitting waiting for you to fix the problem.
Security — To be a member of the security team is to be alternately loved and hated by differing groups in your organization, often different groups at different times. Security generally finds themselves tasked with doing audits of internal data security and setting standards to help achieve compliance with data security standards. Computer forensic applications are the toolbox of the IT Security team; to do the job it will help to be seasoned at data analysis/data mining and event correlation. Security is usually the team tasked with defending audits as well, so it helps if you have good verbal communication skills. Finally, Security is sometimes tasked with coming up with the Disaster Recovery and Business Continuity Plans for a business. In some cases, other departments handle this, but in my experience this has been a Security-type role.
Database Administration — DBA is a tough specialization to be hired in. Brent Ozar has a great blog post covering this, so I won’t go in to too much detail but instead refer you to Brent Ozar’s excellent blog post series linked here. Suffice to say, you need to be able to speak SQL and make it sound like Shakespeare before you can roll with the titans like Mr. Ozar.
Telephony — I’m hesitant to group Telephony into IT, but many times it falls under the moniker of IT, so we’ll cover it here. Telephony is the specialization that handles telephones and telephony technologies. You’re going to want to know the details of how signaling works in PSTN networks, things like TDM, FXO,FXS, E&M, CAS, and a whole lot of other crazy acronyms. Depending on the size of the organization, you might also need to have some cross-pollination with the Networking skillset.
In a future blog post, I will cover what I consider the “elephant in the corner” when it comes to hiring in IT. Remember, it’s not always what you know, but who you know that gets you hired. As always, your comments and criticisms are welcome/encouraged; I’d like to hear what the community feels on this topic.
