Example

Mid-Level Engineer

I'm a software engineer with four years of experience, specializing in frontend development and creating intuitive user interfaces. I'm really passionate about making experiences users love.

At Acme Co, I led the implementation of a design system that reduced UI development time by 30% and ensured consistency across the product. Before that, I worked on a customer feedback platform where I integrated a machine-learning model into the frontend to provide real-time insights.

For my next role I've been looking for a space in healthcare where I can solve tough problems with a user-centric lens and Synertech seemed like a perfect fit.

Notice the personal summary establishes who they are and what they care about. The accomplishments are specific with quantified impact. And the forward-looking statement connects their experience to this specific opportunity.

Senior Engineer

I'm a senior software engineer with over 10 years of experience building distributed systems and scaling complex applications. My expertise lies in designing architectures that work across a large array of teams and use cases.

At Flux, I spearheaded the migration of our monolithic application to a microservices architecture, reducing downtime by 50% and improving team productivity. Previously, I built a real-time analytics platform handling millions of daily transactions, using a combination of Kafka and Elasticsearch. I also enjoy mentoring junior engineers, helping them grow into confident contributors.

To continue using and grow my experience with large scale systems is the goal with my next role. I enjoyed chatting with the engineer I met at the conference last week, so excited to be here.

What determine senior here is:

1. Scope increase cross team
2. Mentoring juniors

[!note]
Don't say negative things about previous employed, describe the motivation for something new, be positive what you're headed toward

Mistake

1. Dont say I work at X and move to Y, now at Z
   • We dont need a walk through here, this makes your older experience as euqal important as your most recent one.
2. I love programming since i was 6
   • No need a biography, starts with who you are professionally now
3. I'm a swe at ABC with X YoE (full stop)
   • Not enough info
4. My current company has problem X,Y,Z
   • Make listener wonder if you're the problem
   • Expose lack of ability to change technical and cultural in your role
   • Say something like this instead

   As I've grown technically, I've become increasingly interested in working on developer tools and infrastructure that can impact how entire engineering teams work. That's what draws me to this role: the opportunity to build in a culture that knows how to ship and is known for technical excellence.

Tell me about your favorite project

Detail description of your daily work over a long period of time. This answer alone has already determine the majority of the behavior

These are the same questions:

1. Tell me about your favorite project
2. Tell me about your most impactful project
3. Tell me about a time when you solved an ambiguous problem

Doesn't matter just reply with the same story. They dont really care which one is your "favorite".

Choosing your "favorite" project

Impact: Choose work that moved meaningful business metrics — could be revenue growth, performance gains, cost savings. Anything with quantifiable specific numbers

Scope:

• Project with substantial breadth or duration that gave you opportunities to demonstrate multiple signal areas.
• Projects that spans weeks, months, involving cross-functional collaboration, both technical and non-technical problem solving

Personal contribution

• You have to be a primary driver, not just a participant
• Being part of high-impact team is not enough, you need clear ownership of significant actions

Sweet spot is to find a project where all three intersect. If we can't find one that has all three, prioritise personal contribution

• A smaller project where you led everything is better than a massive initiative where your role is replaceble

Questions that always comeup

1. Were there any conflicts you encountered?
2. What was the hardest part?
3. What would you do differently?
