Stanza Living Tech Design Engineer Interview: Rounds, Questions and Preparation

What the job involves

Design Engineers in proptech and construction tech translate architectural and interior concepts into buildable, cost-effective designs for co-living, student housing, or managed rental properties. They work daily with CAD/BIM tools, modular furniture specifications, MEP coordination, and site teams to ensure fast, repeatable, and code-compliant execution across multiple properties.

Role and Technical Knowledge

1. 1

   What is the difference between a concept drawing and a good-for-construction (GFC) drawing in a co-living project?

   Explain that concept drawings show intent and layout options, while GFC drawings include dimensions, material specs, MEP routes, and details ready for site execution. Mention version control and approval stamps.

2. 2

   How would you plan a 200 sq ft studio unit for a student housing property to maximise occupancy and comfort?

   Cover bed placement, study desk, storage under bed, kitchenette or shared kitchen strategy, and bathroom ventilation. Show awareness of modular furniture and standard unit sizes for repeatability.

3. 3

   Which National Building Code (NBC) clauses matter most when designing a hostel or co-living building?

   Mention fire safety (staircase width, exits), ventilation, minimum room sizes, and accessibility. Admit if you do not remember exact numbers but show you know where to look.

4. 4

   How do you coordinate a false ceiling design with HVAC ducts, plumbing, and electrical conduits?

   Describe a clash-free approach using BIM or layered CAD drawings, setting ceiling void heights, and holding coordination meetings with MEP consultants before freezing the layout.

Practical Scenarios

1. 5

   A site team says your modular wardrobe design does not fit because the wall is 2 inches off from the drawing. What do you do?

   Show a step-by-step response: visit or video call the site, re-measure, check if a standard filler piece or adjustable leg can solve it, and update the drawing with an as-built revision. Mention informing the project manager.

2. 6

   You have to reduce the cost of a 50-room co-living floor by 10 percent without changing the room count. How do you approach it?

   Suggest value engineering: standardise furniture sizes, switch to locally available finishes, reduce false ceiling coverage, or use drywall partitions instead of brick. Quantify savings roughly and note quality trade-offs.

3. 7

   The client wants a premium look for the lobby but the budget is tight. How do you balance design and cost?

   Focus on high-impact, low-cost elements like feature lighting, accent paint, or a single statement material. Keep other areas simple and repeatable. Show that you can prioritise where the user spends time.

4. 8

   You are asked to design a room that can be converted from a single occupancy to a double occupancy quickly. What design features would you include?

   Mention movable or foldable furniture, provision for an extra electrical point and bed bracket, and a layout that does not block the bathroom or entry. Highlight ease of conversion without civil work.

Behavioural and HR Questions

1. 9

   Tell me about a time you had to revise a design multiple times because of feedback. How did you handle it?

   Use a STAR example from college or internship. Show you stayed calm, asked clarifying questions, and learned to anticipate feedback. Avoid blaming the reviewer.

2. 10

   This role may require frequent site visits to ongoing projects across cities. Are you comfortable with that?

   Answer honestly. If yes, mention you enjoy seeing designs built and learning from site realities. If you have constraints, state them professionally and suggest alternatives like virtual site reviews.

3. 11

   How do you prioritise when you have three urgent drawings to release and a vendor waiting for a clarification?

   Explain a simple framework: impact on site stoppage, deadline, and dependency. Communicate delays early to the vendor and project manager. Show you can ask for help when needed.

4. 12

   Why do you want to work in proptech and construction tech instead of a traditional architecture or civil firm?

   Talk about speed, standardisation, and technology-driven execution. Mention interest in designing for large-scale rental housing and learning BIM or project management tools. Avoid saying traditional firms are boring.

Portfolio and Tools

1. 13

   Walk me through one project in your portfolio where you used AutoCAD or Revit from start to finish.

   Describe the brief, your role, software used, key challenges, and final outcome. Mention any site or cost constraints you solved. Keep it under three minutes.

2. 14

   How do you ensure your drawings are error-free before sending them to the site team?

   Mention a personal checklist: dimensions, layers, title block, revision number, and cross-checking with MEP drawings. Add that you ask a senior or peer to review before release.

3. 15

   What is your experience with Bill of Quantities (BOQ) or cost estimation for interior or construction work?

   If you have internship experience, describe how you calculated quantities for tiles, paint, or furniture. If not, explain the basic method and show willingness to learn company templates.

4. 16

   Which software are you comfortable with for 3D visualisation, and how do you use it in your design process?

   Name tools like SketchUp, 3ds Max, or Revit. Explain that you use them to test proportions and client presentations, but final construction drawings are still done in CAD or BIM.
