After interviewing with Bremik Construction, Anderson Construction, and NW Demolition and Dismantling, I noticed that not all interviews are equally effective. Some interviews made it easy to understand what the company was looking for, while others felt more informal and less clear. Learning about reliability, validity, and utility helped me understand why.

The interviews that worked best focused on real job experiences. Interviewers asked about safety on job sites, working with a team, and how I handled problems in past jobs. These types of questions are more valid because they relate directly to the work being done. According to the U.S. Office of Personnel Management, structured interviews that use job-related questions are better at predicting job performance and are more reliable because everyone is asked similar questions.

Some interviews felt less effective when they turned into casual conversations. While it was nice to talk freely, it was hard to tell how I was being evaluated. When interviews are unstructured, different candidates may be judged in different ways, which lowers reliability. Research shows that structured interviews are generally more consistent and fair than unstructured ones (Arizona HR, n.d.).

From a utility standpoint, interviews that were focused and well-organized were the most helpful for both me and the employer. To improve interviews, employers could use more structured questions and clear evaluation methods. This would make interviews fairer and help companies choose the best candidates

Before this week, I mostly thought of job descriptions as something you skim once when applying for a job and then forget about. After learning more about job analysis and job design, it’s clear that job descriptions play a much bigger role in how organizations function. They are supposed to clearly explain what a job involves, what skills are required, and how success will be measured. When done well, job descriptions help both employees and managers stay aligned.

One major challenge in developing job descriptions is that jobs are constantly changing. As organizations adopt new technology or shift priorities, employees often take on new tasks that were not originally part of their role. Keeping job descriptions up to date requires time, effort, and communication, which many organizations struggle to prioritize. Another challenge is writing job descriptions that are specific enough to be useful, but flexible enough to allow employees to adapt. Overly rigid job descriptions can limit creativity and make employees feel boxed in.

Not having clear job descriptions can create even bigger problems. Without them, employees may be unsure of expectations, which can lead to frustration, poor performance, and conflict. It can also make performance evaluations unfair, since employees are being judged without a clear standard. From a legal and HR perspective, unclear job descriptions can make it harder to defend compensation decisions or respond to discrimination claims, as discussed in the course materials.

One way to overcome these challenges is to treat job descriptions as living documents rather than one-time paperwork. Managers should regularly review and update them with input from employees who actually perform the job. Using job analysis methods, such as interviews or observations, can help ensure descriptions reflect real work instead of assumptions. Clear, updated job descriptions ultimately support better communication, fairness, and employee engagement across an organization.

What Great Companies Show About Work and Management

After looking at the 2025 Fortune Best Companies to Work For list, one company that stood out to me was Edward Jones. A lot of what employees say about working there connects closely to ideas we’ve discussed about human resources (HR) and effective management.

One thing that really stands out about Edward Jones is how much they focus on training and mentorship. Employees aren’t expected to figure everything out on their own. Instead, the company provides structured training and ongoing support, which helps people feel more confident in their roles. This connects to what we’ve learned about employee development and why investing in workers leads to better performance and higher retention.

Another important part of Edward Jones’ culture is trust and communication. Employees often talk about feeling supported and respected by management. This ties directly to concepts like employee engagement and motivation. When people feel heard and valued, they are more likely to stay committed and put in effort at work.

Thinking about my future, I’d want to be the kind of manager who supports their team while still holding people accountable. HR practices such as performance reviews, feedback, and conflict management will be important in helping me do that fairly. I also think one of the hardest parts of being a manager will be handling difficult conversations without damaging trust or morale.

Overall, Edward Jones shows how strong HR practices can shape a positive workplace. It makes it clear that good management isn’t just about results—it’s about supporting people, building trust, and creating an environment where employees can succeed.
