What Cloudflare clients check first in a proposal

They look for proof that you have handled the exact Cloudflare service they need, such as DNS setup, WAF rules, Workers, Pages, or CDN caching. If the job mentions one of these, name it directly instead of saying you can help with Cloudflare in general.
They want to see that you understand the current problem, not just the platform. Mention the likely cause you would check first, such as a bad DNS record, an overbroad firewall rule, a cache misconfiguration, or a Worker route conflict.
They check whether you can work safely on a live site. Say how you would avoid downtime, for example by reviewing the current config, testing changes in a staging zone, and keeping rollback steps ready.
They look for relevant context about the stack behind Cloudflare. If the site uses WordPress, Shopify, a custom app, or an API, mention how that affects caching, SSL mode, redirects, or bot protection.
They notice whether you ask one or two sharp questions that show you know the edge cases. For example, ask if the issue affects the root domain or a subdomain, whether origin is behind another proxy, and whether the problem started after a recent DNS or firewall change.

Common Cloudflare proposal mistakes and better wording

A common mistake is writing a generic promise like 'I can do Cloudflare setup.' Write instead what you will actually inspect, such as DNS records, SSL/TLS mode, cache rules, firewall events, and Worker routes.
Another mistake is guessing at the fix without acknowledging uncertainty. Better wording is 'I will first verify whether the issue is at DNS, edge caching, or origin response headers, then apply the smallest safe change.'
Many proposals ignore the client's current setup and sound like a tutorial. Replace broad advice with a short plan tied to their case, such as 'If your site is behind WordPress, I will check page cache bypass rules for admin, login, and preview URLs.'
Do not overclaim on security or performance. Instead of saying you will 'make the site secure and fast,' say which Cloudflare features you will tune, such as WAF rules, rate limiting, image optimization, cache TTLs, or Brotli compression.
A weak proposal often forgets to mention verification. Write that you will confirm the result in Cloudflare analytics, browser headers, origin logs, or a test request so the client knows you will validate the change.

Cloudflare screening questions and model answers

How would you troubleshoot a site that is returning 520 or 525 errors through Cloudflare?
I would first separate origin problems from Cloudflare edge settings by checking the origin server directly, SSL/TLS mode, and recent firewall changes. Then I would inspect logs for handshake failures, timeouts, or blocked requests and test with a direct origin request and a proxied request. If needed, I would adjust the certificate, origin allowlist, or timeout-related settings and verify the fix with repeat requests.

How do you decide whether to cache a page in Cloudflare or bypass it?
I decide based on whether the content is public, frequently requested, and safe to serve stale for a short time. Dynamic pages like carts, account areas, admin pages, and personalized content should usually bypass cache, while static assets and public pages can be cached with clear rules. I also check headers and query strings so the cache behavior matches the application, not just the URL pattern.

Have you worked with Cloudflare Workers or custom firewall rules before?
Yes, and I usually start by mapping the request flow so the Worker or rule does not interfere with login, API, or asset paths. For Workers, I check routes, environment variables, and error logs; for firewall rules, I review rule order, exceptions, and event logs. My goal is to make the change precise enough that it solves the issue without breaking unrelated traffic.
