Recently, there are many neural networks — how do you use them at work, how often and in what way?

A user sees only one poster on the page — how do we compare it with those they haven't seen (partial feedback)?

Let's brainstorm how to repackage RAG experience for recommendation systems, and then typical questions. Just briefly, not how to answer, but the essence based on my experience and resume.

How does contrastive loss with in-batch negatives work?

How does incremental update of a FAISS index occur in production?

What are items? How is it correctly pronounced?

Write a short paragraph for self-presentation, highlighting that recommendation systems are very similar to RAG - retrieval, reranking, architectural similarities, and so on, so I can remember and explain.

Evaluate how much data is needed for model retraining in production, describe the retraining process, parameters, loss (contrastive/triplet), and why it was chosen.

Formulate and write the definition of roc auc. How is the roc auc score calculated? Write a function that computes roc_auc_score according to the given definition. And for an arbitrary number of classes with a specified priority order? The model works as follows: y_score[i] >= threshold -> y_pred[i] = 1; y_score[i] < threshold -> y_pred[i] = 0.

What to do when a block has a different amount of content — some have single blocks, and others have blocks with 30 items? How to work with content scores to get a feature from this block?

Did I understand correctly: we have a ranker with an average score from the content ranker based on content filling, with user and block features, and we took positive — what exactly?

Please tell us about the project you were involved in and what exactly your role was.

Tell me about your experience, what have you been doing over the past five years?

If you were given an unlimited number of GPUs to improve the system's quality, which direction would you choose first?

Do you know what DSSM is?

Senior

Why was the project developed for two years if you say that the main part was done two years ago? Is the project currently in support or was it further developed?

Senior

Why then will the ranker be trained? That is, will it be independent of the content — what is its target?

# given an array a = [1, 20, 10, 0, 59, 63, 0, 88, 0] -> [0, 0, 0, 1, 20, 10, 59, 63, 88] # write an optimal function that moves zeros to the beginning of the array and preserves the order of the rest def move_zeros_to_left(a: List[int]) -> List[int]: pass
