Interview Questions With Sample Answers

Here are the sample answers to some common questions interviewers may ask you during your planning engineer interview:

1. What is a project baseline?

Interviewers may start with this question to assess your knowledge of basic project management concepts. This may also help them know about your planning skills. You can answer this question by defining the term and providing a suitable example.

Example answer: "A project baseline is the starting point of a project plan. You use this as a benchmark to monitor the progress of the actual project. This can help you determine the overall performance of the project. For example, you determine the project to complete in five weeks, but the schedule baseline has a completion time of four weeks. This may indicate that you require to take measures to complete the project in four weeks."

2. What do you require for developing a project plan?

This question may help the interviewers gauge your understanding of the components essential for project planning. It is important for a planning engineer to be aware of all the essential things that help in the development of a project plan. One way of answering this question is by stating the components in the order in which you may require them.

Example answer: "The first thing that I would require is the contract. It is an important document for understanding the overall requirement of the project. I would then use the schedule drawings to assess the area and the Bill of Quantities (BOQ) to determine an estimated budget for the project. I would also require access to scheduling software to manage project details and updates. Lastly, I would want to meet with the project team to set productivity expectations."

3. What is the difference between free float and total float in project planning?

Interviewers may ask some technical questions to assess your knowledge. This can help them know if you have the required knowledge for the job. You can answer this question by defining both the terms and how they compare to each other.

Example answer: "Free float refers to the amount of delay acceptable before the start of a project activity without affecting the start of the following activity. Total float refers to the amount of delay acceptable for a project without affecting the overall project completion time. While free float may affect a start of an activity or a project, a total float can affect the overall project duration."

4. According to you, what is the greatest accomplishment in your career so far?

Interviewers may ask this question to see how you identify success and setbacks. It can also be an excellent opportunity for you to talk about your significant achievements in your previous role. Try to pick one instance from your previous roles and talk about it. You can also use statistical data if possible to explain your achievement in a quantifiable manner.

Example answer: "At my previous job, there was a big project on which the company was working. After the commencement of the project, I realised that the estimated duration is inaccurate. The budget of the project was also inaccurate because of this. I immediately communicated the error to all the stakeholders and reworked the plan. That helped in saving 20% of the total cost than what we had estimated earlier."

5. Tell us about a time when you made a mistake. How did you resolve it?

This question can help interviewers understand your ability to identify mistakes and work on them. It can also help determine if you have accountability. You can answer this question by talking about an instance where you made a mistake and explaining how you addressed it.

Example answer: "At my previous workplace, I accidentally entered the budget details of one project into another project. As soon as I realised my mistake, I cleared up the budget details from both projects and re-entered the correct details. Throughout the process, I kept my senior updated on the issue."
