今天来看腾讯的开发工程师的初面题。

Q1 - Q9, Q12我感觉这是整张卷子最值钱的部分。面试官非常懂行，他关注的是大模型在实际业务中的控制流和记忆管理。

先说Q1, Q2, Q5。
大模型的 Token 是要算钱且有长度限制的。怎么存用户的聊天记录？
怎么在跨系统、跨时间的情况下，还能让大模型记得用户是谁、之前说了什么？
这是做智能助手最核心的痛点。

Q3, Q4, Q6, Q12。终于开始考架构了。
面试官在考查你对大模型调用框架的底层认知。问 FSM和 LangGraph，说明腾讯需要用强控制、确定性高的流式架构去规范大模型的胡言乱语。
问为什么选 ReAct 而不是纯 Chain，估计是在看面试者对Reason-Action与死板工程流水线之间平衡点的理解。

Q7, Q8，毫无疑问的Skill。
这通常是大型 Agent 框架，比如字节的 Coze、腾讯自己的类似产品里的核心概念，考查的是能不能把复杂的工具调用封装成标准化、可复用的插件。

Q10、Q11，还有Q13。
这应该算是传统后端的知识。
工厂模式、本地部署与配置管理以及后台怎么搭建，是在淘汰那些只会调 OpenAI 接口，但连基本的后端架构、高可用、设计模式都不懂的包装型选手。
腾讯的团队，要的是能直接上手写生产环境代码的熟练工。

Q14、Q15，没啥可说的，算法基本功。
最长有效括号考Stack或者动态规划，挺考验逻辑严密性。
股票交易，也属于LeetCode 经典系列，我经常刷，典型的动态规划、贪心算法。经典的大厂核心算法大礼包，虽然和 AI 没直接关系，但用来刷掉代码基本功不过关的人非常有效。

现在大厂要的 AI 工程师，既要懂大模型的特性，比如Token限制、Agent流控、RAG挂载这些，又要是一个扎实的传统后端高手。
如果能把前 12 道关于 Agent 架构和记忆管理的题解释得既深又透，哪怕后面项目稍微薄弱一点，腾讯那边也会觉得你对大模型应用开发是有深度思考的。

You have Claude Fable for only a few days. Here's how to make the most of it.

Introducing /improve: use your most capable model to audit your codebase and write plans for cheaper models to execute later.

Studies your code, figures out bugs, perf, tech debt, missing tests, what to build and writes plans any agent can run.

🚀不少人遇到 Codex 每次打开或提问时总是先触发 5 次 “Reconnecting” 重连 这个问题。

这个问题的本质原因：WebSocket（WSS）协议在你的网络或代理环境下无法正常通通信。

解决方案有3种：
1. 修改 Codex 的 config.toml，在对应的 provider 配置里明确禁用 WebSocket 并指定 wire_api：

wire_api = "responses"supports_websockets = false

2. 如果使用 Clash verge 的话，直接开启 TUN 模式。
开启后，它会从系统底层接管全局所有流量，强行打通 WebSocket 阻碍。

3. 直接把下面提示词 发给 Codex （具体见文章）

------
帮我修复 Codex Desktop 一直 Reconnecting 的问题。

请定位我本机正在使用的代理端口和代理协议，然后创建或更新 ~/.codex/.env，写入以下代理配置。不要写死端口，请替换成实际端口；如果文件已经存在，保留其他配置。

HTTP_PROXY="http://127.0.0.1:<HTTP 或 mixed 端口>"
HTTPS_PROXY="http://127.0.0.1:<HTTP 或 mixed 端口>"

写入后检查配置是否正确，并告诉我需要如何重启 Codex Desktop。

💡 How Indie Creators Crack the X Algorithm: Tips for Rapid Growth!

[Cooper Ye @yesuxiong]

As indie creators, we all know the X platform (formerly Twitter) algorithm can either make or break you. To grow quickly and attract traffic, you need to learn how to “hack” the algorithm. Here are some practical tips gathered from top creators:

[Cooper Ye @yesuxiong]

4️⃣ Never include links in your first post
The X algorithm penalizes posts with outbound links. If you need to include a link, add it in the second comment instead of the main post to preserve your post’s weight!

[Cooper Ye @yesuxiong]

3️⃣ Maintain a 60% follower-to-following ratio
Following too many people makes you seem less “valuable,” but following too few limits your social reach. Aim for the golden ratio of 60%.

[Cooper Ye @yesuxiong]

2️⃣ Get X Premium (paid verification)
Verified accounts receive a significant boost in visibility. If you want to grow, this is a must.

[Cooper Ye @yesuxiong]

1️⃣ Encourage engagement, especially replies and profile clicks
Research shows that replies and profile clicks carry 13.5 times more weight than likes! Make your content thought-provoking or slightly controversial to encourage people to reply or check out your profile.

Ditch your subscription.
​
I killed 3 startups because of recurring payments:

1. IndiePage:
✅ It makes $4,000/month on autopilot ($45 for lifetime access).
❌ It made $0/month when I priced it at $15/year.
​
2. MakeLanding:
✅ It made $100/day when I launched ($19 per landing page generated).
❌ It made $0 with a $5/month subscription.
​
3. HabitsGarden:
✅ 100% of users chose the $47 lifetime deal.
❌ Nobody buys the $5/month plan.

Business owners love subscriptions. Customers hate them.
​
Here’s the invisible cost of charging recurring payments:
​
- Conversion rate drop: People are reluctant to commit to another subscription, which triggers objections and hesitation.
- Fighting churn: People lose interest soon after signing up. Instead of a steady income, you’re constantly replacing customers who cancel.

Selling a $10/month monthly subscription is as hard as selling a $100 one-time payment.
​
Let’s assume you built an excellent SaaS (10% churn = 10% of your customers cancel at the end of the month).

Imagine you get 100 customers today:
- You’ll earn $7,176 with subscriptions, after 365 days.
- You earn $10,000 with one-time payments, right now.
​
Subscription doesn’t mean recurring revenue. If you’re working solo, in 99% of cases you’re better off financially with one-time payments.

One-time payments alternative
​
Sometimes, your business has recurring costs, and you can’t afford one-time payments. I’m not talking about bandwidth (that’s negligible) but things like AI credits or database costs.
​
Then try credits-based pricing:
​
- Let your customers pay upfront for what they’ll use. Generate 10 AI photos for $5.
- Then, add a Good-Better-Best package. 100 AI photos for $20 ($.2/photo looks cheap now).
​
This removes the subscription friction (which boosts your conversion rate) and helps you avoid constantly fighting churn.

When subscriptions make sense
​
👔 B2B: If you’re selling to businesses, subscriptions make sense because the end goal of any business is to make money.
🤕 Complex credits: When tracking credits is too complex or it’s hard to quantify what your customers use.
​
Subscriptions serve a specific purpose. Recurring payment = Recurring value according to my friend @DanKulkov.

Just because competitors charge recurring payments doesn’t mean you should. Remember, people are tired of subscriptions, and purchase behavior is changing. Not charging a subscription can be a competitive edge.
​
Oh, and entrepreneurs flex on each other with MRR charts. It’s a status game, don’t fall for it. In the end, the customer is king.
