Hiring in the age of AI-assisted coding: what works?
I saw the HackerRank (YC S11) hiring post (https://news.ycombinator.com/item?id=47667011) and it made me realize I no longer understand how to evaluate candidates effectively.Specifically, we are changing hiring across 3 dimensions: > Tasks: Real-world tasks on code repositories vs standard algorithmic-style puzzles > Evaluation: AI fluency, orchestration skills vs functional correctness > Candidate experience: Agentic IDE vs a simple code editorIn the “old world,” you could ask multiple questions and triangulate skill from answers. Now it seems like evaluation depends heavily on tools and models that keep changing month to month.So I’m curious: > What signals actually correlate with strong engineers today? > How do you design interviews that don’t become obsolete with the next model release? > Are algorithmic interviews still useful at all?Would love to hear from people who have recently changed their hiring process or have been interviewed using this new approach.

A critical problem in evaluating AI-fluent engineers exists, but the 'idea' is a research question, not a buildable product.
The pain
The gap
Build angle
Strengths
- Extremely relevant and urgent problem in a rapidly growing market.
- High willingness to pay for effective solutions due to the cost of mis-hiring.
- Clear, specific user frustrations with existing 'old world' assessment methods.
Risks
- The idea itself is a research question, not a product, making it unbuildable as-is.
- Highly crowded market with numerous funded incumbents already addressing parts of the technical hiring space.
- Defining 'AI fluency' and designing assessments that remain relevant as AI models evolve month-to-month is a continuous, complex challenge.
Next steps
- Shift the idea from a research question to a concrete product or service proposal. For example, 'A SaaS platform that offers real-world, agentic-IDE based coding challenges specifically designed to evaluate AI orchestration skills'.
- Conduct in-depth interviews with hiring managers who explicitly state they are struggling with evaluating AI-fluent candidates to gather more specific pain points and desired features.
- Explore the technical feasibility of creating an 'Agentic IDE' environment and real-world task simulations for assessment, considering the rapid changes in AI tools.

A real, urgent problem exists in evaluating engineers for AI-assisted coding, with a potential gap for a tool focused on new evaluation criteria. However, the idea as presented is a research question, not a product idea suitable for building.
Value Equation
Dream outcome and how likely it feels, against the time and effort it costs.
High market potential for a *solution* in this space, but the idea itself is a research question, not a monetizable product or offer.
One-Person Business
Curiosity pull, identity fit, and a path from free value to paid for a solo creator.
The problem is exceptionally clear, but the 'idea' itself is a research question, making it unassessable as a solo-runnable business under Koe's framework.
Viral Frameworks
Hook strength, shareability, and how cheaply it can be tested.
This idea defines a clear problem for a specific audience but lacks a product, value proposition, or business model, making it unviable as a micro-SaaS.
Builder Lens
Evidence the problem exists, timing, defensibility, and a model that fits on a napkin.
The problem described is real and becoming more critical, but the idea is a foundational inquiry rather than a testable product.

Market signals
The market for AI-assisted coding hiring tools is growing rapidly, driven by the increasing demand for developers with AI skills and the need for objective, scalable assessment methods. Recent trends include a shift towards real-world task simulations over algorithmic puzzles, AI-powered evaluation for code quality and efficiency, advanced plagiarism detection for AI-generated code, and conversational AI interviews.
What frustrates people
- HackerRank tests can feel disconnected from real development work.
- HackerRank's emphasis on competitive programming problems doesn't always reflect real-world developer tasks or broader system design skills.
- Top candidates may refuse HackerRank tests due to the extra assessment stage feeling unnecessary.
- CodeSignal's pricing is fully custom and enterprise-level, which can be a barrier for growing teams.
- Codility's per-invite pricing scales poorly at volume.
Semble – Code search for agents that uses 98% fewer tokens than grep
Hey HN! We (Stephan and Thomas) recently open-sourced Semble. We kept running into the same problem while using Claude Code on large codebases: when the agent can't find something directly, it falls back to grep, reading full files or launching subagents. This uses a lot of tokens, and often still misses the relevant code. There are existing tools for this, but they were either too slow to index on demand, needed API keys, or had poor retrieval quality.Semble is our solution for this. It combines static Model2Vec embeddings (using our latest static model: potion-code-16M) with BM25, fused via RRF and reranked with code-aware signals. Everything runs on CPU since there's no transformers involved. On our benchmark of ~1250 query/document pairs across 63 repos and 19 languages, it uses 98% fewer tokens than grep+read and reaches 99% of the retrieval quality of a 137M-parameter code-trained transformer, while being ~200x faster.Main features:- Token-efficient: 98% fewer tokens than grep+read- Fast: ~250ms to index a typical repo on our benchmark, ~1.5ms per query on CPU (very large repos may take longer)- Accurate: 0.854 NDCG@10, 99% of the best transformer setup we tested- MCP server: drop-in for Claude Code, Cursor, Codex, OpenCode- Zero config: no API keys, no GPU, no external servicesInstall in Claude Code with: claude mcp add semble -s user -- uvx --from "semble[mcp]" sembleOr check our README for other installation instructions, benchmarks, and methodology:Semble: https://github.com/MinishLab/sembleBenchmarks: https://github.com/MinishLab/semble/tree/main/benchmarksModel: https://huggingface.co/minishlab/potion-code-16MLet us know if you have any feedback or questions!

Postgres extension for BM25 relevance-ranked full-text search
Last summer we faced a conundrum at my company, Tiger Data, a Postgres cloud vendor whose main business is in timeseries data. We were trying to grow our business towards emerging AI-centric workloads and wanted to provide a state-of-the-art hybrid search stack in Postgres. We'd already built pgvectorscale in house with the goal of scaling semantic search beyond pgvector's main memory limitations. We just needed a scalable ranked keyword search solution too.The problem: core Postgres doesn't provide this; the leading Postgres BM25 extension, ParadeDB, is guarded behind AGPL; developing our own extension appeared daunting. We'd need a small team of sharp engineers and 6-12 months, I figured. And we'd probably still fall short of the performance of a mature system like Parade/Tantivy.Or would we? I'd be experimenting long enough with AI-boosted development at that point to realize that with the latest tools (Claude Code + Opus) and an experienced hand (I've been working in database systems internals for 25 years now), the old time estimates pretty much go out the window.I told our CTO I thought I could solo the project in one quarter. This raised some eyebrows.It did take a little more time than that (two quarters), and we got some real help from the community (amazing!) after open-sourcing the pre-release. But I'm thrilled/exhausted today to share that pg_textsearch v1.0 is freely available via open source (Postgres license), on Tiger Data cloud, and hopefully soon, a hyperscalar near you:https://github.com/timescale/pg_textsearchIn the blog post accompanying the release, I overview the architecture and present benchmark results using MS-MARCO. To my surprise, we were not only able to meet Parade/Tantivy's query performance, but exceed it substantially, measuring a 4.7x advantage on query throughput at scale:https://www.tigerdata.com/blog/pg-textsearch-bm25-fu

Consus (YC F24) – LLM gateway for companies handling sensitive data
Hey Hacker News! I'm Eric, the founder of Consus. We route all AI requests to ITAR restricted and controlled unclassified information (CUI) compliant infrastructure. Consus itself satisfies ITAR restrictions, and we recently completed our FedRAMP equivalency audit against the 410 FedRAMP High controls. FedRAMP High is the U.S. government’s strictest security baseline for cloud services handling sensitive unclassified data. A breach of this data could cause severe or catastrophic harm. Achieving FedRAMP equivalency, or authorization, is required before processing CUI information.Demo: https://youtu.be/6MYxJe6P4oYAerospace and defense is experiencing rapid growth. Unfortunately, most companies are struggling to use AI because of necessary data protections & compliance risk. These companies can move even faster if they could use the AI tools that most other industries take for granted.I spent most of my career prior to Consus in aerospace & defense. I launched national security payloads at SpaceX, and was an early employee at Castelion. I’ve watched first hand how compliance red-tape makes it difficult for companies to adopt new technologies and trust vendors that touch their sensitive data. For example, I worked with a satellite manufacturer that doesn’t allow any AI tools, even for non-sensitive work.Even as AI has become extremely useful over the past 9-12 months, I was surprised by how many aerospace & defense companies refused to touch it. They could see how it could be helpful, but they were scared about model providers training on their data, violating an ITAR rule, or risk losing new business because of a failed cyber assessment. These are all rational fears.There were a lot of ways to solve some/all of these problems, but we focused on building a compliant AI inference layer that can "plug" into any AI tool or workflow. Just as OpenRouter integrates with most tools, Consus can connect to tools like ChatGPT or Clau
