A Full Stack Web Developer was asked
Q. What is Time Complexity? Give examples.
Ans. 

Time complexity measures the amount of time an algorithm takes to complete as a function of the input size.

  • Time complexity is expressed using Big O notation (e.g., O(n), O(log n)).

  • O(1) - Constant time: Example - Accessing an element in an array by index.

  • O(n) - Linear time: Example - Finding an element in an unsorted array.

  • O(n^2) - Quadratic time: Example - Bubble sort algorithm.

  • O(log n) - Logarithmic time: Example...

Q. Given an array of numbers, find the smallest Prime Number.
Ans. 

Find the smallest prime number in a given array of numbers.

  • A prime number is greater than 1 and has no divisors other than 1 and itself.

  • Example: In the array [4, 6, 8, 3, 5], the smallest prime is 3.

Q. What is the time complexity of adding an element to a Singly Linked List?
Ans. 

Time complexity to add an element to a Singly Linked List is O(1) if added at the end using Tail pointer, and O(n) if added anywhere in the middle.

  • Adding an element at the end of a Singly Linked List using the Tail pointer is a constant time operation, hence O(1).

Q. Design and implement a data structure for Least Recently Used (LRU) cache. It should support the following operations: get(key) - Get the value (will always be positive) of the key if the key exists in the ...
Ans. 

LRU Cache is a data structure that stores the most recently used items and discards the least recently used items.

  • Use a hash table to store key-value pairs

  • Use a doubly linked list to keep track of the order of items

Interview Preparation Tips

Interview preparation tips for other job seekers - For the Coding round, build your logical thinking skills rather than counting how many questions you solved. (I solved only 17 Hackerrank questions prior to the interviews (2 days ago) that to based on array, linked list, q, stack, and tree).

For Technical 1, DSA is a must, know your basics. While optimizing a particular problem, try to use Hashmap.

For Technical 2, Know your project very well, If you have not contributed to your project, and if you are not eager to learn about it, then you are doomed for rejection. So learn about it.
And you always know that there is a certain part of the project which you could have designed well, So study about it, because they will ask you to optimize it.

For HR, be true and honest about yourself.

Interview Tips & Stories

a team lead
Why are women still asked such personal questions in interview?
I recently went for an interview… and honestly, m still trying to process what just happened. Instead of being asked about my skills, experience, or how I could add value to the company… the questions took a totally unexpected turn. The interviewer started asking things like When are you getting married? Are you engaged? And m sure, if I had said I was married, the next question would’ve been How long have you been married? What does my personal life have to do with the job m applying for? This is where I felt the gender discrimination hit hard. These types of questions are so casually thrown at women during interviews but are they ever asked to men? No one asks male candidates if they’re planning a wedding or how old their kids are. So why is it okay to ask women? Can we please stop normalising this kind of behaviour in interviews? Our careers shouldn’t be judged by our relationship status. Period.
