What's included
Three pieces that work together
Copy once, get everything. Learners prepare on their own, you answer questions live, and the surveys tell you what stuck.
Self-paced course
Short lessons with real workplace scenarios, not walls of text.
- 6 lessons, about 45 minutes
- Sorting activity, scenario, timeline, accordion and quizzes
Live session deck
An AhaSlides presentation to run after the course, in person or online.
- 10 slides
- Quiz, poll, ranking, word cloud slides
- A closing slide for your contacts
Two surveys
Find out what landed, and whether people use it on the job.
- Post-course feedback, about 2 minutes
- 30-day check-in
- Anonymous by default
- Results feed your next refresher
Learning objectives
At the end of this course, learners can
Each objective and the lesson that covers it.
| ID | Objective | Source | Where it's covered |
|---|---|---|---|
| TO 348.0 | Achieve ≥ 80% on the final assessment | - | Whole course |
| SO 348.1 | Describe running time growth in plain language (constant, linear, quadratic) | Best practice | Whole course |
| SO 348.2 | Choose between searching and sorting approaches for a given size and need | Best practice | Whole course |
| SO 348.3 | Pick a list, stack, queue, hash table or tree for a stated use | Best practice | Whole course |
| SO 348.4 | Spot a slow nested loop in a code sample and propose a faster approach | Best practice | Whole course |
| SO 348.5 | Explain a data structure choice in a code review + your info | Organisation's engineering standards | Whole course |
Your part: what a template can't do for you
- Your workplace details: fill in the 5 highlighted fields so the course describes your own policies, contacts and locations.
- Records: record completion in your own LMS or record system.

Live deck and surveys
10 slides to run live, two surveys to close the loop
Pink slides are interactive. Both surveys are anonymous; pink questions are written for this course.
Post-course feedback: 11 questions, about 2 min
- Overall rating 5 stars
- Relevant, realistic, right length, helpful activities agree/disagree grid

- Confidence before this course, and now 1-5 scale
- Confidence in Big-O · searching and sorting · lists and stacks · hash tables · profiling grid
- How often do you check performance with large data? multiple choice
- Which slow code are you aware of? short text
- I can say ‘I do not know the complexity of this’ without feeling judged. 1-5 scale
- One thing we should change or add open text
- Would you recommend this course? NPS
30-day check-in
- Have you used what you learned since the course? multiple choice
- How confident are you today? Compare with day 1 1-5 scale
- Do you know where to find the engineering standards and profiling tools? yes / no / not sure

FAQ
Common questions
Can I run algorithms, data structures and complexity for working engineers training online?
Yes. The course is self-paced and online, and the live deck lets you add a live session in the room or online.
How often is this training needed?
At onboarding of new engineers, and before a performance-focused project.
Who needs this training?
New engineers, bootcamp graduates and developers who choose data structures in production code; run by engineering managers with L&D.
What records should I keep?
Record completion in your own LMS or record system, so you can show who finished the course and when.
Can I edit the content?
Yes, everything. Change the wording, swap scenarios for ones from your workplace, add your logo, or remove parts that don't apply.
