I Tested an AI Resume Builder Against Big Tech Interview Bloggers

I follow a handful of 大厂面试 博主 (big tech interview bloggers) on Bilibili, mostly to keep up with what interview rounds look like now. One thing they keep repeating: most resumes get screened out before a human ever reads them. That's why I ended up testing Jobly, an AI resume builder, instead of just watching another video about bullet points.

I went in skeptical. These tools usually generate text that looks clean and says nothing specific. But I wanted to see whether jobly could actually produce a resume that matches what those bloggers recommend — quantified results, STAR structure, no clutter.

What I actually tested

I built a realistic profile: a mid-level backend engineer with two years of experience, one open-source project, and a stalled application to a major tech company. I gave jobly rough notes and let it create the resume and a cover letter from scratch. Then I ran the results through the checks the 大厂面试 博主 crowd actually cares about — plain-text ATS parsing, formatting consistency, and whether the bullets survived a second look.

Jobly AI resume builder: the checklist

• Bullet rewriting is the best part. I fed it "responsible for the user login module." Jobly turned that into a STAR-style bullet with user impact and a suggested metric. That saved me the most tedious part of resume editing.
• But it will invent numbers. The same output contained a "12% reduction in login failures" that I never gave it. I caught it and removed it, but it wasn't obvious at first glance. If you rush, that goes straight into your application.
• The formatting holds up. I pasted the result into a plain-text checker and it parsed cleanly — no broken tables, no weird columns. That alone puts it ahead of half the templates I've seen shared online.
• The cover letter is average. The first draft was so generic it could have applied to any company. I had to feed it more details about the role before it became something I'd send.
• The free tier is real. The ai resume builder free version let me generate several drafts and test most features. Only the nicer templates and a few export options were locked behind the paid upgrade.

What the 大厂面试 博主 crowd would still fix

My main reservation isn't the output quality. It's the workflow. Jobly drafts fast, but it doesn't verify anything. Fact-checking its work took me real time — the kind you're tempted to skip when you're tired of editing.

There's also a sameness problem. Several bullets followed the exact same pattern, and any experienced resume reviewer would spot that template feel quickly. I'd rewrite at least half of what it generates in my own voice before sending it anywhere.

Is a free ai resume maker 2026 worth it?

I'm still a bit torn. If your background is solid but your resume is weak, a free ai resume maker like jobly is a decent first move. It turns a blank page into something you can argue with, which is easier than starting from nothing.

But I wouldn't let the tool be the final step. Take the draft, correct every single fact, and run it past someone who has actually been through a big tech interview loop. That part hasn't changed. Use jobly to build the draft, then treat it like a coworker who works fast and occasionally exaggerates — review everything, delete suspicious numbers, and rework phrases until they sound like you. As a starting point for a 大厂面试 博主-approved resume, that's a fair trade.
