Do you think veterans are viewed as superior to other candidates for technology positions?

It depends on the Veteran's experience and the company. One of the challenges is the separation of responsibility in the military which can often result in a limited skill set for the Veteran. There are many larger companies that have multiple groups that manage their technology and a veteran can specialize, and in that case I'd see the military service as a leg up on the competition, especially if they already have a security clearance. For smaller companies where breadth of experience is as important as depth, I don't think the military experience would put the Veteran in a higher tier of candidate. For smaller hi-tech companies, there's often a need for skills in the latest and greatest technologies. I don't know many Veterans who have built highly scalable node.js systems or implement distributed NoSQL databases - it's just not in the technology wheelhouse for most of the military unless you're working in cyber or info warfare. As a Veteran that runs a global engineering group in the EU and US, I want to favor Veterans in my highly selection, but it's difficult to find in those coming off of active duty the right kind of skills for the technologies we use.

I've experienced superior, but have been told otherwise as well by peers (in their quest to find employment). It seems to depend on who's hiring, and their background.
If I was a hiring official or recruiter for a company, and I worked in the same field, I would definitely prefer veterans (in my case, Data Marines), since I would know exactly what to ask them, their field experience, and determine if they are qualified. I've mentioned this on a topic or two here on RP.

I believe being a veteran can help with employments in technology position, but not significantly. Employers care more for education and experience background. Being a veteran will place you over an equally qualified candidate. Depending on the company that you are applying for, holding an active security clearance is a huge incentive to pick you over another candidate due to the amount of cost and time that is required to clear a freshly picked up civilian. It is also common belief in large companies that military background in the technology field usually does not translate to what you will do on the civilian side.

I contracted with a company that works in Aerospace while in my Junior year in an Engineering major. While I was applying for internship with the said company, the networking with management and other engineers from within the company, and my education background, played a much larger factor than my military service. Being a veteran does work in favor for you as many companies do prefer employing veterans; just don't overestimate how much more competitive the status makes you.
