Round 2 - Technical 

(6 Questions)

  • Q1. (interviewer observed that i am nervous. so, he did some small talk, i presume to make me feel comfortable)
  • Q2. (after describing a project on my resume) explain recall in plain english? why did you use recall as evaluation metric? how do you calculate recall for mutli-label data? how did you decide the number of hi...
  • Ans. 

    Recall is a metric used to measure the ability of a model to find all relevant instances in a dataset.

    • Recall is the ratio of true positives to the sum of true positives and false negatives.

    • It is used as an evaluation metric to assess the model's ability to identify all positive instances correctly.

    • In multi-label data, recall can be calculated for each label separately and then averaged.

    • The number of hidden layers and n...

  • Q3. What is universal approximation theorm?
  • Ans. 

    Universal approximation theorem states that a neural network with a single hidden layer can approximate any continuous function.

    • A neural network with a single hidden layer can approximate any continuous function

    • It is a fundamental theorem in the field of deep learning

    • The theorem applies to a wide range of activation functions

    • The number of neurons required in the hidden layer may vary depending on the complexity of the ...

  • Answered by AI
  • Q4. How does backpropagation in neural networks work?
  • Ans. 

    Backpropagation is a supervised learning algorithm used to train neural networks by adjusting weights to minimize error.

    • It involves propagating the error backwards through the network to adjust the weights of the connections between neurons.

    • The algorithm uses the chain rule of calculus to calculate the gradient of the error with respect to each weight.

    • The weights are then updated using a learning rate and the calculate...

  • Answered by AI
  • Q5. In what scenarios would you advice me to not use ReLU in my hidden layers?
  • Ans. 

    Avoid ReLU when dealing with negative values or vanishing gradients.

    • When dealing with negative values, use Leaky ReLU or ELU instead.

    • When facing vanishing gradients, use other activation functions like tanh or sigmoid.

    • In some cases, using ReLU in all layers can lead to dead neurons.

    • Consider the nature of your data and the problem you are trying to solve before choosing an activation function.

  • Answered by AI
  • Q6. Some questions on Named Entitiy Recognition(NER)
Round 3 - Technical

  • Q2. How will you get the embeddings of long sentences/paragraphs that transformer models like BERT truncate? how will you go about using BERT for such sentences? will you use sentence embeddings or word embedd...
  • Ans. 

    To get embeddings of long sentences/paragraphs truncated by BERT, we can use pooling techniques like mean/max pooling.

    • We can use pooling techniques like mean/max pooling to get embeddings of truncated sentences/paragraphs.

    • We can also use sliding window approach to get embeddings of overlapping segments of the long input.

    • For using BERT on such long inputs, we can use sentence embeddings or word embeddings depending on t...

  • Q4. If you were an animal or bird, which one would you want to be and why?
  • Ans. 

    I would want to be a dolphin because of their intelligence, social nature, and ability to swim freely in the ocean.

    • Dolphins are known for their high level of intelligence and problem-solving abilities.

    • They are highly social animals and live in groups called pods.

    • Dolphins have the ability to communicate with each other using a complex system of clicks, whistles, and body movements.

Interview Preparation Tips

Interview preparation tips for other job seekers - interviews have been a lot practical, which i prefer to asking definitions that are just a google search away. if you do not answer to something, explain only that you know to the extent you do or just tell the interviewers that you do not know. intervieweres have also been more interested in my approach to the questions i did not have proper answers for. and interviewers didn't have a prepared set of questions, it was all spontaneous based on the projects on work, based on what I uttered. be prepared to answer and explain every word that come out of your mouth. questions may arise from anything. interviewers counter-question all that you explain, you must be able to explain why that can't be the case and why whatever that you have done makes more sense and fits the problem at hand.

be humble and calm, behaviour goes a long way.
