What actually happens in an AI Engineer interview? In this video, you’ll see a real mock interview — not just questions, but how candidates are evaluated in real time. We go beyond answers and focus on: • How to break down AI/ML problems • How interviewers assess your thinking • Follow-up questions that test depth • Common mistakes candidates make If you're preparing for AI Engineer, Machine Learning, or LLM roles, this is exactly the kind of interview experience you need. Watch till the end to understand how top candidates stand out.

I thought this interview was more around Generative AI. I need interview on Applied AI involving agents not just RAG. Thanks for this btw. Would love to have someone from top tech company etc. for this if its possible.
Corrections: KNN is implied as clustering algorithm while it is actually a supervised classification algorithm.

KNN Is a supervised classification algorithm not clustering.
We can improve attention by using two separate techniques 1. memory Saving technqiues: (comparison still O(n^2) but fast due to less blocks) a) MQA --> multiple query but one key and value blocks b) GQA --> multiple query but grouped key-values blocks 2. reducing time complexity: a) random attention (attending random tokens from a current one and not all) b) sliding window (attending the prev and next tokens only within the respective window) c) there are many variants of sliding window d) Linear Attention (we do Q(Kᵀ V) instead of (QK^T)V)
pls make a video on ai system design is it same to software system design
He has no idea of what he is saying. Just throwing in random technical jargons
Please bring more such videos! Its such a great help to someone like me who is a fresher and stuggling with the job market and interviews right now :)
That's a great video..but his ans were a bit outdated.....and he is not going indepth to explain the differences...
20:40 KNN typically uses Euclidean distance to identify the nearest data points to a given query point. In contrast, cosine similarity measures the angular difference between vectors rather than the absolute distance between their endpoints. Consider two vectors that have a very small angle between them but differ significantly in magnitude—one is short while the other is long. Using Euclidean distance, the endpoints of these vectors may appear far apart, suggesting low similarity. However, from a directional perspective, the vectors are actually quite similar because they point in nearly the same direction. In such cases, relying solely on Euclidean distance can be misleading. Cosine similarity is often more effective because it focuses on orientation rather than magnitude by computing the cosine of the angle between vectors and the query vector. Of course, in practical systems, cosine similarity is not computed against every vector exhaustively. Various optimization and indexing techniques are used to efficiently retrieve the most relevant vectors.
please make more similar videos
very informative, please keep this series continued
Hi, Thank for the Mock Interview , Just one suggestion : Please in end of the video provide the question - response specifically those are incorrect response from candidates
hi sir can u bring next interview video on ai generalist
For 100 documents question can't we just first parse those details and map those details into a database using a model and then when user gives a query we generate a SQL query for it and extract the relevant data for the user query from the database?
the question was not clear more for classification of review , said 500 then it is not real time data ,so it it is simple suprvised problem , we have data set that has features then we are going to use classical mL for classification and there is parameter one versus rest for multiclass , it we have just 2 columns one is for text and other is target then need emedding but word2vec or Glove not provide contexual embedding which will might wrong classification regards
and how someone use for such limited data neural archtiecture RNN, or its varients even said transformer .... so if it is text embedd it and bring it into tabular fom use any ML algorithm for classification
Please make more videos ❤
Very good learning and exposure to how AI/ML interviews are! Thank you very much for making this available for us.
