The first round consisted of mcqs based on English, cs fundamentals and aptitude. Also, there were couple of coding questions from arrays and pattern-printing (both easy - medium).

From the shortlisted students, we were segregated into different batches to conduct GD round. The topic was general. They are looking for your behaviour more than your fluency. Be respectful and kind to your fellow mates, share your thoughts without fearing much. They give a chance for the introverts if they are being totally silent because of the extroverts. (Behaviour + content > talking endless crap)

Q1. After some more shortlisting... This is unconventional, but I did like the approach. After the GD round, it was a Technical + HR round (they might conduct in the usual order for you, meaning first Technica...read more

Q1. Q1. Implement python Collection Counter from Scratch.
Ans. 
Implementing Python Collection Counter from Scratch
• Create an empty dictionary to store the elements and their count

• Iterate through the input list and add elements to the dictionary with their count

• Return the dictionary

• Example: input_list = ['apple', 'banana', 'apple', 'orange', 'banana']

• Output: {'apple': 2, 'banana': 2, 'orange': 1}

Q2. Q2. Do Matrix Multiplication. Q3. Implement Factorial and Fibonacci Series with different Approaches.
Ans. 
Matrix multiplication, factorial and Fibonacci series implementation
• Matrix multiplication involves multiplying two matrices to get a third matrix

• Factorial is the product of all positive integers up to a given number

• Fibonacci series is a sequence of numbers where each number is the sum of the two preceding ones

• Factorial can be implemented using recursion or iteration

• Fibonacci series can be implemented using recursion or

Q3. Q4. What is the probability of getting 5 Sundays in 31 day month.
Ans. 
The probability of getting 5 Sundays in a 31 day month is less than 1%.
• There are 7 days in a week, so the probability of any given day being a Sunday is 1/7.

• In a 31 day month, there are 4 full weeks and 3 extra days.

• The probability of the first 4 weeks having 4 Sundays is (1/7)^4.

• The probability of the remaining 3 days being Sundays is (3/7).

• Multiplying these probabilities gives a total probability of less than 1%.

Q4. Q5. There were 100 coins. 99 Unbiased Coins, 1. Coin is biased. Derive the probability of getting 10 heads given the even of unbiased coins using Bayes Theorem.
Ans. 
Using Bayes Theorem, find the probability of getting 10 heads given 99 unbiased coins and 1 biased coin.
• Identify the prior probability of getting 10 heads with unbiased coins

• Calculate the likelihood of getting 10 heads with the biased coin

• Use Bayes Theorem to calculate the posterior probability of getting 10 heads given the mix of coins

• Consider the impact of the biased coin on the overall probability

Q2. Q2. What will be the approach If all the features are categorical in Linear Regression. Q3. What is Dummy variable trap? If we don't remove dummy variable what will be the issue and does it impact performa...read more
Ans. 
Categorical features in Linear Regression require encoding using dummy variables. Removing one dummy variable avoids the dummy variable trap.
• Categorical features need to be encoded using dummy variables to be used in Linear Regression

• Dummy variable trap occurs when one dummy variable can be predicted from the others

• Removing one dummy variable avoids the issue of multicollinearity and improves model performance

• Example: ...read more

Q3. Q4. You are standing in a field. Chances of seeing atleast 1 plane in 10 minutes is 15%. What is the probability of seeing atleast 1 plane in next 30 minutes?
Ans. 
Probability of seeing a plane in 30 minutes given 15% chance in 10 minutes.
• Calculate the probability of not seeing a plane in 10 minutes

• Use the formula P(X>=1) = 1 - P(X=0)

• Calculate the probability of not seeing a plane in 30 minutes using the above probability

• Calculate the probability of seeing atleast 1 plane in 30 minutes using the formula P(X>=1) = 1 - P(X=0)

Q4. Q5. If we select a random point in a circle of 1 unit radius what is the probability of appearing that point closer to the circumference , not closer to the centre.
Ans. 
Probability of a random point in a circle of 1 unit radius being closer to the circumference than the center.
• The probability is 1/4 or approximately 0.785.

• This is because the area of the circle closer to the circumference is 1/4th of the total area.

• This can be calculated using the formula for the area of a circle: A = πr^2.
