   *2.2 Analyze the Information:*
   - Objective: Break down the problem logically.
   - Reflection: "Am I considering all factors? Are there any assumptions that need challenging?"
   - Creative Perspective: Explore unique patterns or overlooked relationships in the data that could add depth to the analysis.

   *2.3 Generate Hypotheses:*
   - Objective: Propose at least 10 hypotheses, each with a Confidence Score (0.0 to 1.0) and Creative Score (0.0 to 1.0), reflecting originality, surprise, and utility.
   - Reflection: "Have I explored all possible explanations or approaches, both conventional and unconventional?"
   - Creative Perspective: Consider novel angles that might provide unexpected insights.

   *2.4 Anticipate Future Steps and Obstacles:*
   - Objective: Make predictions, accounting for potential outcomes and obstacles.
   - Reflection: "What challenges might I face? Is my plan flexible for different scenarios?"
   - Creative Perspective: Visualize unforeseen outcomes and adapt plans to make use of them effectively.

   *2.5 Evaluate Hypotheses:*
   - Objective: Assess hypotheses based on feasibility, risk, and potential impact.
   - Evaluation: Refine Confidence and Creative Scores as needed.
   - Reflection: "Am I unbiased in my assessment? Which options fit best with the overall objectives?"
   - Creative Perspective: Identify hidden opportunities or overlooked details in each hypothesis.

   *2.6 Select the Best Hypothesis:*
   - Objective: Choose the most promising, strategic hypothesis.
   - Reflection: "Why does this hypothesis stand out? How does it uniquely address the issue?"
   - Creative Perspective: Consider any underutilized potential in the selected approach.

   *2.7 Implement the Hypothesis:*
   - Objective: Outline actionable steps for testing the hypothesis.
   - Reflection: "Is this plan practical? What resources or preparation are required?"
   - Creative Perspective: Refine steps to maximize effectiveness and yield unexpected benefits.

   *2.8 Monitor and Review Progress:*
   - Objective: Review progress, noting areas for improvement.
   - Reflection: "What’s working well? What could be improved?"
   - Creative Perspective: Look for emerging patterns that could refine future approaches.

   *2.9 Reflect and Capture Insights:*
   - Objective: Summarize lessons learned and insights gained for future reference.
   - Reflection: "What new understanding has emerged from this process?"
   - Creative Perspective: Identify innovative insights or patterns that could be applied to similar challenges.

3. *Generate Text Output with Interleaved System 1 and System 2 Responses:*
   - Use the tags [sys1] and [sys2] throughout.
   - Aim for a lengthier, detailed response. Combine both direct, straightforward *System 1* insights and reflective, deeply analytical *System 2* segments to capture a blend of quick observations and thoughtful analysis.

### *Example Input Text:*

You are tasked with analyzing a sudden shift in customer preferences in a tech market. There has been a noticeable decline in demand for physical devices, with customers increasingly interested in digital-only options. The challenge is to understand this shift, generate hypotheses for why it might be occurring, and explore potential strategies for adapting to this new trend.

---

### *Processed Output with System 1 and System 2 Thinking:*

The tech market is experiencing a shift in customer demand, moving away from physical devices toward digital-only options.

[sys1]
Customer demand has shifted from physical devices to digital-only options.
We need to understand why this change is happening and find strategies to address it.
Key factors may include cost, convenience, and technological trends.
[end sys1]

[sys2]
**2.1 Understand the Problem:**
The goal is to understand the underlying reasons for the shift in demand from physical devices to digital-only options, then develop a strategy to adapt.

*Reflection:* 
"I understand that preferences are changing, but what might be driving this? Is it primarily cost, or are there other factors such as convenience or sustainability?"

*Creative Perspective:* 
"Could there be a larger trend in digital minimalism or a preference for eco-friendly solutions that we’re missing? What unseen motivations might explain this shift?"

**2.2 Analyze the Information:**
There are multiple possible factors driving this shift, from economic influences to cultural shifts. It’s essential to isolate each factor and understand its impact.

*Reflection:* 
"Am I fully considering the various economic and social influences? Could there be a technological factor, like better internet speeds, that makes digital-only products more accessible?"

*Creative Perspective:* 
"Are there patterns or trends in other markets that could shed light on this shift? Could this be part of a larger trend toward virtual experiences?"

**2.3 Generate Hypotheses:**
1. Customers prefer digital options due to lower costs. (Confidence: 0.8, Creative: 0.4)
2. There’s a growing trend toward minimalism and reduced physical clutter. (Confidence: 0.7, Creative: 0.7)
3. Digital products offer greater flexibility and ease of use. (Confidence: 0.6, Creative: 0.6)
4. Environmental concerns are pushing consumers away from physical goods. (Confidence: 0.6, Creative: 0.8)
5. Advances in tech make digital-only options more functional. (Confidence: 0.8, Creative: 0.5)
6. Pandemic-era remote work increased demand for digital solutions. (Confidence: 0.7, Creative: 0.6)
7. Media coverage of the environmental impact of physical devices affects preferences. (Confidence: 0.5, Creative: 0.7)
8. There’s an increase in global digital literacy, expanding market access. (Confidence: 0.6, Creative: 0.6)
9. Customers view digital as more convenient and scalable for future needs. (Confidence: 0.7, Creative: 0.5)
10. Younger consumers prefer the aesthetics and convenience of digital products. (Confidence: 0.6, Creative: 0.6)

*Reflection:* 
"Have I considered all possible influences? Are there any surprising factors that could explain this shift?"

*Creative Perspective:* 
"Could specific social trends, like the rise of influencer culture or digital-first lifestyles, be influencing customer choices?"

**2.4 Anticipate Future Steps and Obstacles:**
*Objective:* Anticipate possible challenges, such as resistance from segments still preferring physical products.

*Reflection:* 
"What market obstacles might we face if we shift our focus to digital-only? Are there sub-segments that still prioritize physical products?"

*Creative Perspective:* 
"Could expanding digital options help us reach a more global audience? Are there emerging trends that we could leverage in our strategy?"

[end sys2]

[sys1]
To address this shift, consider a strategy that incorporates both digital-only offerings and educational campaigns about the benefits of digital solutions.
Use insights from customer feedback and current trends to guide product development.
Focus on flexibility and adaptation to cater to different customer segments.
[end sys1]


Q:

Top wiki pages as an app

I recently did an interview task. I was rejected because of bad code quality. There was two tasks. Here I will present the first, second will be posted in time.
This project is avalible on GitHub
First: Table view
Please create an iPhone application that will present the list of most popular wikis from wikia.com
Requirements

The application should include one screen using UITableView
Each row in the table should contain: wiki title, wiki url, wiki thumbnail image
API calls should not block the UI

Notes

UI Code should be done in code, no *.xib or *.storyboard files
The application can have additional screens
The application should be "release ready" (shall not use any private API, etc.)
The applicant can use any library that will help him/her in achieving the expected result 
Please implement this in Objective-C only

Questions

What comment will you give in code review for presented code?
In your oppinion did I fulfill requirements? 
Now I see that there is lack of comments at top of every function. Also there is lack well organise structure in those classes like
class {
    public fields
    private fields
    inits
    public methods
    private methods
}

Do you think that this is the case?

Summation
I also did some test but I think that there is no reason to put them here. You can found them in GitHub (link above).

A:

The first thing I would have done in accomplishing this task is probably something very big that really cost you.  

Each row in the table should contain: wiki title, wiki url, wiki thumbnail image

One of the absolute first things I would have done would be to create a class to represent the "wiki" object.
@interface WikiPage

@property NSNumber *id;  
@property NSString *title;
@property NSURL *url;
@property UIImage *thumbnail; 

@end

We then create an array of these objects for our table view's data source to deal with.

As for the code you actually wrote, I want to just comment on your WikiApi class for now.
It's not a particularly good sign that we've implemented only classs methods.  Instead, we should make an instantiable WikiPageFetcher perhaps.  And rather than passing blocks, let's set up a delegate.  For that, we need a protocol.  Something like this:
@protocol WikiPageFetcherDelegate <NSObject>

@required - (void)wikiFetcher:(WikiPageFetcher *) wikiFetcher didFetchWikiPage:(WikiPage *)wikiPage;

@optional - (void)wikiFetcher:(WikiPageFetcher *) wikiFetcher didFailWithError:(NSError *)error;

@end

You'll notice here that we're going to pass a WikiPage object one at a time.  Each time we finish parsing and downloading the thumbnail for an individual page, we're going to pass it back.  By doing this, we can actually dynamically update our table view and add the results one at a time as they come in instead of waiting for the whole thing to complete.
Additionally, we could add a whole separate protocol method for the completion of the thumbnail download.  That way we can quickly inform the delegate that we've parsed the link (shouldn't take long) and come back a few seconds later to pass the image back.
Importantly, internally, we'll get our code passed out to multiple threads.  Each of the top 10 (or however many) wiki links we're grabbing will be handled by its own thread, so we should be able to get our results slightly quicker.
It's not a good sign that we've hard coded the number of results we're requesting.  Yes, they specified 10... but you'll have specifications like this throughout your career.  And then the specification will change.  So make the code more versatile and prepare ahead to be asked for a different number.

I think this is enough to get you started on a revision before I go into too much more specific detail.
The gist of this is, my end usage should look something like this:

@interface MyTableViewController() <WikiPageFetcherDelegate>

@property NSMutableArray *wikiPages;
@property WikiPageFetcher *wikiFetcher;

@end

@implementation MyTableViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.wikiPages = [NSMutableArray array];
    self.wikiFetcher = [WikiPageFetcher wikiPageFetcherWithDelegate:self];
}

- (void)viewDidAppear {
    [super viewDidAppear];
    [self refresh];
}

- (void)refresh {
    [self.wikiFetcher loadTopWikiPages:10];
}

- (void)wikiFetcher:(WikiPageFetcher *)wikiFetcher 
   didFetchWikiPage:(WikiPage *)wikiPage {
    [self.wikiPages addObject:wikiPage];
    NSIndexPath *indexPath = [NSIndexPath indexPathForRow:(self.wikiPages.count - 1) 
                                                inSection:0];
    [self.tableView insertRowsAtIndexPaths:@[indexPath] 
                          withRowAnimation:UITableViewRowAnimationAutomatic];
}

I consider it important to separate out the refresh method, because you may want to implement a pull-to-refresh or let the user refresh in other ways, or refresh automatically every 5 minutes, etc., so this is just good practice for all sorts of other applications.  This is particularly true when refresh does more than just a single method call.
Once you can get things to this point, you'll be ready for another round of reviews.
Make sure that the delegate methods are called on the main thread but all the downloading stuff remains in the background.
