For now, here are the main interview questions that you’re likely to receive.
1.) Software Engineer Interview Questions & Answers
Q1: “What is the biggest project you’ve worked on? What was your role in that project? What was the most difficult element?”
A1: “I was once thrown into the role of project manager for a critical client project. It was unexpected, but I appreciated that my manager believed in my ability to shift gears and bring the project together. It was certainly a challenge coordinating the project, but my team and I pulled through.
As a developer, learning new skills and technologies is something I take part in on a weekly basis. Having that experience allowed me to step out of my comfort zone and made me feel more confident in my ability to one day take on a lead or senior position.”
Q2: “What is the difference between a repository server and a powerhouse?”
A2: “A repository server’s main point is to guarantee the reliability and uniformity of the repository. On the other hand, a powerhouse server deals with executing various procedures between factors of the server’s database repository.”
Q3: “Discuss several best practices in design and development for Informatica.”
A3: “Modularity is important to keep in mind – using reprocessing techniques and common error handling, for example. Scalability should always be considered when utilizing caching, partitioning, and querying. Making frequent use of reusable Informatica components like workouts, mapplets, and reusable transformations will allow quick reactions to changes.
As far as development practices go, using local variables will limit redundant calculations, leaving detailed comments in code helps everyone working on that project, and using the filter transformation as close to the source as possible is more efficient.”
2.) Technical Support Engineer Interview Questions & Answers
Q1: “Do you prefer working independently or in a team?”
A1: “I’m comfortable working both in a team and independently. Some tasks and projects are accomplished more efficiently with independent research and work while others benefit from a team-centric environment. Having other people to bounce your ideas off and to view the project from another perspective can often be helpful.”
Q2: “What is the Informatica ETL Tool?”
A2: “ETL stands for “Extract, transform, load” and it represents the three components of data preparation. Deriving business intelligence from data is made possible by the ETL tool. This is the main component of Informatica and the key to businesses programmatically analyze their datasets.”
Q3: “Have you ever had an issue working with a member of your management team?”
A3: “I rarely have issues with management. However, when they occur, they are generally easily solved with better communication from both parties. I did have one manager who would always take her personal issues to her work place as well. It seemed to create negativity in the work environment. Nonetheless, I didn’t allow it to affect me too much because I understood she was simply going through a difficult time. The situation presented issues with keeping up the morale of the team, however.”
3.) QA Engineer Interview Questions & Answers
Q1: “How do you handle tight deadlines and stress?”
A1: “I work well under pressure because having a number of upcoming deadlines and assignments to finish motivates me to stay on task and be productive. Feeling productive motivates me more than anything – I always want to be pulling my weight as a member of my team. The key to managing stress in such situations is to balance project deadlines carefully. Separating large projects into smaller tasks and scheduling them out so that everything is finished on time is a method that works well for me. Over the years, time management allowed me to finish my assignments before they were due.”
Q2: “What is the difference between an active transformation and a passive one?”
A2: “An active transformation can change the number of rows that pass through transformations, change transaction boundaries, and change the type of the row. Passive transformations don’t perform any of these actions.”
Q3: “Tell me about a time you had an issue with a member of your team and how you resolved it.”
A3: “A new member of my old team was having issues letting go of his old company’s development practices. Many of my coworkers would become irate with him after running into his code. After a while, it got to the point where they wouldn’t even talk to him. This new employee was a highly-skilled engineer, but no one was respecting him because of his failure to adhere to the new standards.
I sympathized with him because design and development standards can almost become part of your muscle memory after working at a company for a while. I ended up staying with him after work in 30-60 minute chunks to help him get the hang of the new standards. After a month, the team was working together more smoothly.”
