I attended IK and I've got a lot of knowledge that helped me get into Microsoft. TheirCurriculum (algorithms and data structures) is organized very well and explanations are so helpful. Andmock interviews and the feedback helped me a lot. It was worth it!

Neetika Srivastava

Software Engineer

Placed at:

I really like how the program is structured and how it caters to different domains. It is really helpful. The patterns that they teach you at Interview Kickstart are really useful because you can apply those patterns to any new problem. Knowing those patterns, you can solve basically any question because you can relate it to problems you have already solved, which gives you confidence.

Chun Wu

Senior Software Engineer

Placed at:

I joined iK after stumbling across it while reviewing some other interview prep materials after doing poorly in an interview at Linkedin. I knew that doing well in these interviews would require dedication and investment of my time - but with so many resources online I didn't have structure. This is what the IK platform provided me.

Shrey Shrivastava

Software development Engineer ll

Placed at:

The Interview Kickstart course is very structured and informative. They teach you about DS and algo fundamentals very thoroughly and also prepare you for the software engineering interview. I really like the live classes by FAANG engineers, and the homework and tests definitely help you toprepare for a real interview. If you have been looking for a bootcamp that prepares you for software engineering interviews, I would say this is definitely the right place to do it.

Sridhar Gandham

Senior Software Engineer

Placed at:

My experience at IK was extremely positive. I was preparing for FAANG companies using the standard techniques that you find on the internet. When I started preparing, there was no structure to the madness. For example, a simple quicksort can be implemented in multiple ways. So solving a medium problem would take me about 30 minutes. The biggest benefit that I got from IK was a clear, structured way of solving problems. After IK, I could solve medium problems in 10 minutes!

Frequently Asked Questions

What to Expect at iOS Engineering Interviews

The iOS interview is typically conducted in three main phases:

Recruiter screening

This is the first round involving informal discussions with a recruiter from human resources once your profile is shortlisted.
In this round, you can expect a few basic questions on your experience, technical skills, compensation, etc.

Online assessment

The online assessment round is commonly known as the technical screening
It involves remotely solving a coding assignment via a screen-sharing remote interview, a shared doc, or online coding platforms such as Codeforces or HackerRank.
A hiring manager who is driving the recruitment for iOS Developers conducts this round.
Apart from writing error-free, workable code to the problem statement, your ability to answer open-ended questions and ask insightful clarifying questions is also evaluated in this round.

On-site rounds

The on-site interview is the final round consisting of 4-5 interview rounds where recruiters evaluate your coding, client-side system design, iOS domain knowledge, and behavioral skills. As such, on-site rounds vary a lot for each company.

Algorithmic coding round: Depending on the years of experience, candidates go through 2-3 coding (DSA-based) rounds. Usually, the difficulty level of these questions is in the Leetcode(LC) easy/medium level, but you can occasionally expect LC hard questions too. You will be expected to solve the questions using Swift/Objective C, which are the primary languages used for iOS Development.
iOS-specific rounds: These rounds can be a mix of pop quizzes, bug fixing, code slicing, live coding, and system design questions. A detailed description of these types of questions can be found below. Note that FAANG companies focus only on iOS pop quiz questions and system design-type questions, while other Tier-1 companies have a mix and match of all the following types of questions.

iOS pop quiz questions: This will test your iOS fundamentals. You will be grilled on your knowledge of iOS Development- Design patterns, Views, and User Interaction.
Live coding: Code a feature of an application from scratch.
Bug fixing: This will involve Fixing bugs in a given app codebase within a given time interval.
Slicing of code: This short round will typically involve explaining the working of a given piece of code.
iOS systems design rounds (generally for experienced candidates): The number of design rounds typically increases with your work experience and applied level. Candidates are expected to design the client side of real-world applications such as Twitch, TikTok, WhatsApp, etc.

Behavioral interview: This is usually the final interview where hiring managers will ask you questions about challenging projects you worked on, how you handle professional challenges, workplace ethics and conduct, and leadership.

To excel in the on-site interview, you must have:

A thorough understanding of Objective-C and Swift, as well as iOS standards and best practices
Library/Toolkit Experience: iOS SDK, Figma, HomeKit, CloudKit, Cocoa Touch
Working knowledge of the difference between synchronous and asynchronous tasks within iOS
Sound knowledge of core data structures, algorithms, and scalable systems design
