It’s all too easy to overlook mistakes in your own writing because its difficult to be both an author and an editor of the same text. That’s true of any written communication such as a covering letter, personal statement, email, essay or any message that you write. Mistakes are particularly common in CVs (or résumés) because they are so personal. You can spend hours carefully polishing the words and the formatting but not see a fatal error at the top of page one. Hacking20 other people’s CV’s will help you debug and improve your own. You may need to use ingenious hacks like the temporary fix to the bridge in figure 15.1. Fixing other peoples bridges will help you improve your own bridges, see section 0.5.1. You’ll build better bridges to more interesting and ambitious destinations.

## 15.1 Hack their CVs

A useful hacking technique is to take somebody elses stuff and fix or improve it. That works for written communication as well as actual code. The dogfooding technique described in section 4.6.1 is a useful hack which you can use by:

2. Eating somebody elses dogfood by:
• Hacking a friends or peers CV by swapping with them and giving them constructive feedback
• Hacking the fictitious CVs below by ranking them against a job advert in section 15.4. Who would you want to interview and why?
4. Persuade someone else to eat your dogfood - get feedback from as many people (and bots see section 6.7.6) as you can

So, here are some fictitious CVs for you to hack, from students of Computer Science. They are based on CVs I’ve seen, warts and all, with personal information removed and anonymised. Can you spot their triumphs and tragedies? Can fix their CVs and work out which candidate is best for the sample job description at CoolTech in section 15.4? Can you hack their future?

Special thanks to Toby Howard and Sean Bechhofer for coming up with some of these silly names for fictional students of computing. Please direct any complaints about the terribly geeky puns to Toby and Sean! Can you spot all the bad jokes? Thanks also Ben Carter and Penny Gordon Lanes in the careers service at the University of Manchester, some of these CVs are based on examples they have collected and anonymised. 🙏

## 15.2 Breakpoints

Let’s pause here. Insert a breakpoint in your code and slowly step through it so we can examine the current values of your variables and parameters.

* PAUSE ⏸️

When you read these CVs make a note of:

1. What Went Well? (WWW) What do you like about any given CV, what have they done well?
2. Even Better If? (EBI) What could be fixed or improved, can you hack it?
3. Their Rank order (1,2,3...) Who is top of your list to interview? Who is going in the bin and why?
* RESUME ▶️

Imagine the person is real, what would you tell them about their CV if they’d given it to you for advice without hurting their feelings? How could you be a critical friend by giving them actionable feedback?

## 15.3 Sample CVs

### 15.3.1 Penelope Tester

Penny Tester, or Pen as her friends call her, loves cybersecurity and reverse engineering. She has a real passion for finding vulnerabilities in software and hardware. Just don’t call her a hacker she dislikes that word, see figure 15.2.

### 15.3.2 Rick Urshion

Rick is a big fan of functional programming and loves solving problems with languages like Lisp, Haskell, Clojure, Erlang and Scala. He really doesn’t like side-effects but tries to avoid getting into a state about it. Critics say he can be inefficient but Rick insists he’s just lazy, see figure 15.3. Rick’s father and grandfather were also called Rick, and his great-grandfather was too. You’ll never guess what Rick and his partner are going to call their son…

### 15.3.3 Marge Conflict

Marjorie loves version control because Marge is the master of the merge. She also has very high emotional intelligence (EQ). This superpower enables her to recognise emotions in herself and others so that she can quickly resolve people’s differences, see figure 15.4.

Resolving people’s differences is an important skill, not just for git merge shown in figure 15.5, but any kind of team collaboration where some kind of conflict is inevitable.

### 15.3.4 Michael Rokernel

Mike lives in Los Angeles and loves operating systems, but not if they get too bloated, see figure 15.6.

### 15.3.5 Florence Ting-Point

Flo loves maths and is a particularly big fan of floating-point arithmetic, see figure 15.7.

### 15.3.6 Peter Byte

Peter Byte and his twin sister Peta Byte, both love big data, machine learning, statistics, data science and Artificial Intelligence (AI). They come from a big family with eleven other siblings including Deca, Hector, Kilo, Megan, Giga, Terry, Exa, Zita, Yotta, Rona and Quetta. The byte family are wildly ambitious, but critics say they have been terribly over-hyped, see figure 15.8.

### 15.3.7 Polina Morphism

Polly loves object-oriented programming. She has lots of siblings, and a cousin called Isa. Instead of a CV or résumé, Polly has put some basic details on her LinkedIn profile which she primarily uses for professional social networking, see figure 15.9.

### 15.3.8 Neil Pointer

Neil is a mature student who loves the C programming language, see figure 15.10. The Pointer family are sometimes misunderstood, but Neil compensates for this with his excellent memory management skills and efficiency. As well as twin sister Noelle, he also has three famous sisters, and a younger half-brother, Neil Pointer-Exception, from his fathers second marriage. Neil Pointer-Exception prefers Java. Noelle and Neil Pointer have seen many programming languages come and go, but their favourite will always be C. Like C, Neil is a child of the 1970s, easily “old enough to be your father” or (if he was a woman) your mother. Respect your elders!

### 15.3.9 Bryn Hanby-Roberts

The last CV is a real one. Bryn kindly gave his permission to share it with you, see figure 15.11. Bryn graduated in 2016, his CV is longer as he has five years of experience under his belt but it provides a useful counterpoint to the examples above. Thanks Bryn. 🙏
