Things To Keep in Mind While Going to an BIM Interview

The journey of a job interview is a pivotal moment that shapes your career trajectory. Whether you are a fresher or a seasoned professional, the interview process is a crucial step to new opportunities. However, it’s not about just rehearsing your resume. But about representing yourself authentically while demonstrating your skills to your potential employer. 

The competition is more fierce than ever and you must equip yourself with the right mindset and effective job search strategies to stand out from the crowd. Read further to learn the things to keep in mind while going for an interview.

1. Update Your CV and Portfolio 

Keep your CV and portfolio up-to-date with your latest projects and ensure that you can explain your portfolio confidently. While many interviewees bring digital copies of their work, it’s advisable to have a hard copy of your portfolio to prevent potential technical issues. 

2. Do Your Homework

Familiarise yourself with the company’s background and do in-depth research on the projects they do to prepare yourself for organisation-related questions. You can also engage in conversations with current employees to gain insights into the company’s work culture. 

3. Be Honest and Keep Your Interaction Conversational

Maintaining a smooth conversation with the interviewer ensures that there are no awkward pauses and makes the interviewer more interested in you. Being completely honest about your experiences and qualifications and giving in-depth answers helps the interviewer understand your value system and work ethic. 

4. Answer Briefly and to the Point 

Keep your answers concise and to the point. The interviewer isn’t interested in unnecessary details and may get bored by your approach. Ensure you capture the interviewer’s attention and use it to your benefit.

5. Don’t Pretend to Know About Something That You Don’t 

The person interviewing you is most likely a field expert, so there is no way that you can bluff your way around them. If you don’t know about a particular BIM tool or plug-in, just be honest and say that you have no idea about it and you will try to find more information about the same.

10 Most Asked BIM Interview Questions in 2024 

It's best to prepare for specific standard questions to be able to ace your BIM interview questions. This will instil confidence in you and increase your chances of getting hired. Below is a list of 10 commonly asked BIM interview questions in the civil engineering industry and sample answers that will help you prepare better for your interview.

Q1. Could you tell me a little more about yourself?

This is the most common opening question for any interview. Although it may seem like a simple question, this is your opportunity to grab your interviewer’s attention. Keep your answer concise, ideally at most thirty seconds. Instead of just talking about your academic experiences, you could also talk about workshops and events that you attended and interests that you have (again, without going overboard). Preparing for this question beforehand gives you a better chance of creating a lasting impression on your interviewer.

How to Prepare Your Answer?

• Recall your academic and personal experiences and mention how they have shaped you as an individual. 
• Highlight your interests and expertise. 
• Relate your technical and soft skills to the company’s needs and create a narrative that aligns with the goal of the company. 

Sample Answer:

“I am XYZ, and after my graduation, I worked for two architectural firms where I realised two things. First, landing a high-paying job in the architecture industry is difficult, and second, there is a major gap in technical expertise, which slows down the way people function. I was fascinated by BIM and decided to pursue my interest. I eventually enrolled in a BIM professional course and upskilled myself. I have hands-on experience with software like Rhino, Grasshopper, and Revit. I have done personal projects and internships related to BIM to gain relevant experience. I have also worked on my soft skills and can effectively communicate, collaborate, and manage with particular emphasis on time management..“

Firstly, I am well-versed in several BIM software, including Revit, ArchiCAD, Navisworks, Dynamo, and SketchUp Pro. I understand the potential of BIM tools and have experience in creating models for various residential and commercial projects. In a recent project, I collaborated with a design team to create an intricate Revit project for improved visualisation. Additionally, I ran simulations to assess the energy efficiency of the structure, adding a comprehensive layer of analysis. Secondly, I have problem-solving skills and an eye for detail, which allows me to identify errors and areas of improvement easily.

Q3. How do you guarantee the accuracy and regular updating of data in your BIM models?

Accuracy is a major BIM component, and interviewers would want to know whether you have the necessary skills to achieve project accuracy. This will help them understand your process and how you handle data, building trust in your ability to keep data up-to-date. 

How to Prepare Your Answer?

• You can start by explaining how you use BIM software like Revit and AutoCAD to ensure that the components within the model are accurate and how you review and update the model regularly. 
• Mention any particular process that you follow to ensure models are error-free, like using automated error detection.

Sample Answer:

“I use BIM software to ensure accuracy in all model components. I review the model and make necessary changes regularly, ensuring that any changes made are reflected in the model.  I also use an automated system to detect errors and double-check measurements so that there are no discrepancies.”

Q4. How do you use clash detection tools to identify potential conflicts between various design elements within a BIM model? 

Clash detection is a pivotal part of the design process. Your interviewer would be interested in understanding how familiar you are with the process and tools to identify and resolve potential conflicts. This interview question for a BIM modeller is an excellent opportunity for you to showcase your problem-solving skills.

How to Prepare Your Answer?

• Begin by explaining how you use tools to identify potential conflicts between design elements like columns, walls, and pipes while developing a design. 
• Talk about your method to analyse clash detection tests and how you resolve issues with your team members. 
• Additionally, give an example of a project where you used clash detection and how it led to the project's success.

Sample Answer:

“I use clash detection tools to detect and analyse conflicts and work with other team members to resolve the issues. I have extensive experience using this method for multiple residential and commercial projects, and I have been able to resolve clashes effectively, saving both time and effort.”

Q5. What methods do you use to improve the performance of large BIM models? 

BIM models are complex to handle, so the interviewer would want to understand if you have the skills to optimise and manage the performance of models. This interview question aims to check whether you have the technical skills needed to accomplish large-scale projects.

How to Prepare Your Answer? 

• Begin by discussing optimising techniques like minimising elements/resources or using components instead of individual objects and the impact on model performance.
• Mention plug-ins or tools that help you streamline the process and talk about best practices for optimisation.

Sample Answer:

“I use various methods to ensure that models are optimised, like reducing the number of elements or using components. I use multiple plug-ins and tools that can be used to streamline the process, like Revit for 3D modelling or Navisworks for clash detection and follow best practices like avoiding unnecessary geometry or maintaining components within a unified coordinate system”.
