In Java, why shouldn't you use strings to store a password?
While this may seem like a rudimentary question regarding your knowledge of Java, your interviewer is looking to ideally hear that you understand the principle differences between string and character arrays. Asking about the storage of passwords within a system gives you the opportunity here to point out the differences between the two. In the end, while explaining the differences, be sure to tie it back to the original question on why strings shouldn't be used to store passwords.

Ryan's Answer #1
"To store a password, character array is the obvious best choice because character arrays are mutable. If a string was utilized to store passwords, a definite security risk would be present to anyone that would have access to the memory dump from the system."
Ryan's Answer #2
"This question simply boils down to a string being immutable. Because strings are a sequence of characters represented as a single data type, the system requires garbage creation to fully get rid of it out of memory. In my time designing software, I have used Char array and its mutable features to store passwords for the security of our end users "

Do you have experience working with data in a cloud computing environment?
Over recent years, more and more companies are converting to cloud based computing services because the conversion allows them to save money and have better auditing trails. As a prospective data engineer with Pegasystems, your interviewer will be looking to hear that you are at least familiar with the concepts of working with cloud based data. Talk in details about the experiences you have while keeping your mind open to working with more in the future if hired with Pegasystems.

Ryan's Answer
"My current organization has been using Apprenda, a PaaS, that allows us to develop, test and maintain our software projects. I also have experience mining and converting data off of public, community and private cloud networks. If hired here at Pegasystems, I think I would bring a wealth of cloud based experience to the data engineering team."
3.
What do you consider to be a good litmus test for when you would automate a test process for a new system versus testing manually?
As your role with Pegasystems will look to help further their automate testing processes for new systems, you will need to have a good sense for when automation makes sense and when it does not. Reiterate your sense for this to your interviewer by sticking to the high level response that repetitive tasks, as are common with large software companies, are prime candidates for automation whereas one time test cases are not.

Ryan's Answer #1
"Having been in automation in both manufacturing for many years and now software for the last three years, a common misconception among people is that automation can help improve any situation and that couldn't be further from the truth. The amount of time, effort and resources that goes into an automation process makes it ideal for repetitive tasks and tests that have multiple data sets. If a testing process calls for unique and one time process, it would make the most sense to run that process manually."
Ryan's Answer #2
"I"n my current position, most of the automation testing that I design is in program sanity testing. These automated tests work great because they run on similar systems following changes in code to ensure that no bugs remain in the system. If our group of engineers are working on unique, one off type projects, my automation processes are not utilized."

How have you handled obstacles that you've faced during information gathering processes in your time as a technical writer?
To successfully document and write about software products, information gathering from subject matter experts will be a key part of your process if hired for this role at Pegasystems. As you have likely experienced during your career, the information gathering process can be one of the most painstaking processes within the life of a project. For this question, your interviewer is looking to hear what obstacles you have faced in this situation in the past and how you handled those situations. This will give them insight on how you will work as part of a larger team in handling these perceived obstacles if hired for this position.

Ryan's Answer #1
"Because the information gathering phase is a vital step in my finished projects, I take the time to meet as many credible sources as possible. This includes design engineers, automation engineers, product designers and many other folks and the biggest hiccup that I usually come across is coordinating time with folks that have busy schedules. To help minimize the total time frame for info gathering, I am very direct in my communications to key leaders that I want to meet with to finish a project and my directness is always taken well. Like any obstacle we face in our work, I find that being upfront and direct is the best manner for handling them."
Ryan's Answer #2
"I'd say that one of the more common obstacles that I have faced in my current role as a technical writer is a lack of expectations from the experts that I consult with through the process. To better this over time, I have created a set of general expectations that I provide to people ahead of our meetings that help them prepare information ahead of time. This approach not only helps me get more relevant information up front, but also helps speed the information process up significantly."

Would you say that you are a goal oriented on the job? What would I be able to do as your manager to help you achieve your goals if hired here at Pegasystems?
At the heart of this question lies your interviewers desire to see what motivates you as a potential employee at Pegasystems. Make it clear to your interviewer that you certainly are motivated by on the job goals and do this by using an example of a time where you were motivated by and achieved a goal. Then, think deeply about the type of manager that you like to work for in terms of goal setting and helping our achieve your goals. Let your interviewer know what type of management styles you appreciate the most while being open to any style.

Ryan's Answer #1
"I would definitely say that I am goal oriented on the job in wanting to contribute any way that I can to the overall benefit of the organization. In my current organization, our leadership focuses on overall sales numbers at the end of the year. To help achieve these goals, our department creates our own goals to help achieve the sales numbers needed to succeed. Last year, one of those goals was to be as creative as possible in our user experience design processes. With the launch of an exciting new app midyear, sales numbers skyrocketed and our department was instrumental in that. For me, it was important that we determined our goals as a team with the final stamp of approval from our manager. While this style of management really helped motivate me, I can thrive under any management style as long as expectations and goals for my work are clearly set."
Ryan's Answer #2
"For me, my day to day work is much more meaningful when I have goals to work for. In my current role, we have set timelines for our projects and this helps lay the framework for our goals. If hired for this position, my expectations of you as my manager would be to have goals clearly defined and a supportive atmosphere to be provided to work within."
