Talk to a coach from your target company for:
The Phone screen is a 45-minute telephonic interview with the recruiter. Here, the recruiter asks questions related to your CV and work experience, if any. The main goal of this exercise is to see how motivated the candidate is for the job and to see if he or she is a good fit for the company and the job. People who are just out of college should be very careful with their CV and any projects or internships they may have had while they were there.
Most asked interview questions in the Initial Screen.

- Why Twitter?
The technical screen is a one-hour interview with the hiring manager and a Twitter software engineer. This round is aimed at assessing your technical skills in the following areas:
Coding
There will be questions on the technical screen that test the candidate’s general programming skills in the “coding aptitude” section. The focus will primarily be on object-oriented programming. Students need to be proficient in at least one of the programming languages among C++, Java, and Python. Typically, the interviewer asks 2-3 coding questions that need to be attempted through a shared online code editor.
System Design
Systems design includes things like system architecture, product design, modules, interfaces, and data that a system needs to meet certain needs. Companies like Twitter are looking for people who are good at system design to help them solve real problems by putting what they think they know to use. The interviewer may ask questions on front-end design, back-end design, scalability, and more in this section.

- Give a list of integers as input, and make a new list where each item at index i is the product of all the numbers in the first list except the one at i.
- If you are given an array a[] and a number p, you need to write a function that counts how many times p appears in a[].
- Here’s the code to add an item to the middle of a linked list:
