What is the Best Way to Start Preparing for SWE Interviews with No LeetCode Experience?

Start with basics: data structures, algorithms. Spend 2-3 months on LeetCode, 1-2 hours daily.

At Google, new grad SWEs without LeetCode experience often struggle in initial interview rounds. A common scenario is a candidate who, despite having a strong computer science background, fails to solve a medium-difficulty LeetCode problem within the given time frame. For instance, in a recent interview for a Google SWE position, a candidate with no prior LeetCode experience was asked to solve the “Validate IP Address” problem. The candidate spent over 20 minutes trying to solve it but ultimately failed to provide a working solution. This highlights the importance of practicing LeetCode problems to improve problem-solving skills and speed.

In contrast, a candidate who had spent 3 months practicing LeetCode problems, dedicating 1-2 hours daily, was able to solve the same problem in under 10 minutes during an interview. This demonstrates the significant impact that dedicated practice can have on improving one’s chances of passing SWE interviews. It’s also worth noting that this candidate started with basic data structures and algorithms, such as arrays, linked lists, and sorting, before moving on to more complex problems.

How Long Does it Take to Get Good at LeetCode and Be Ready for SWE Interviews?

3-6 months, 1-2 hours daily. Focus on most common problems, such as arrays, strings, and linked lists.

The amount of time it takes to get good at LeetCode and be ready for SWE interviews can vary significantly from person to person. However, with consistent practice, most candidates can develop a strong foundation in 3-6 months. It’s essential to focus on the most common problem types, such as arrays, strings, and linked lists, as these are frequently encountered in SWE interviews.

For example, at Amazon, SWE interviewers often ask questions that involve manipulating arrays or strings. A candidate who has practiced these types of problems extensively will be better equipped to handle such questions. Additionally, practicing with a timer can help simulate the time pressure of an actual interview, allowing candidates to improve their speed and efficiency.

Can I Get a SWE Job at a Top Company like Google or Amazon with Zero LeetCode Experience?

Yes, but it’s rare. 1 in 10 candidates without LeetCode experience get hired. Focus on building a strong foundation in computer science and programming.

While it’s possible to get a SWE job at a top company like Google or Amazon with zero LeetCode experience, it’s relatively rare. According to Google’s hiring statistics, only about 1 in 10 candidates without prior LeetCode experience are able to pass the interview process and get hired.

To increase their chances, candidates should focus on building a strong foundation in computer science and programming. This includes developing a solid understanding of data structures, algorithms, and software design patterns. Additionally, candidates should be prepared to learn and adapt quickly, as the interview process for top companies is highly competitive and demanding.

What is the Average Salary Range for New Grad SWEs at Top Companies?

$120,000 - $180,000 per year, depending on location and company.

The average salary range for new grad SWEs at top companies can vary significantly depending on factors such as location and company. However, according to data from Glassdoor, the average salary range for new grad SWEs at top companies like Google, Amazon, and Microsoft is between $120,000 and $180,000 per year.

For example, at Google, the average salary for a new grad SWE in the Bay Area is around $160,000 per year, while at Amazon, it’s around $140,000 per year. Additionally, companies like Palantir and Airbnb tend to offer higher salaries, with averages ranging from $180,000 to $200,000 per year.

How Many Interview Rounds Can I Expect for a SWE Position at a Top Company?

3-5 rounds, including phone screens, coding challenges, and on-site interviews.

The number of interview rounds for a SWE position at a top company can vary, but typically includes 3-5 rounds. These rounds may include phone screens, coding challenges, and on-site interviews, each designed to assess different aspects of a candidate’s skills and experience.

For instance, at Facebook, the interview process typically consists of 4 rounds: an initial phone screen, a coding challenge, a technical interview, and a final on-site interview. Each round is designed to evaluate a candidate’s problem-solving skills, coding abilities, and fit with the company’s culture and values.

Preparation Checklist

Practice LeetCode problems for 1-2 hours daily, focusing on most common problem types
Review computer science fundamentals, including data structures and algorithms
Work through a structured preparation system, such as the PM Interview Playbook, which covers key topics like system design and behavioral questions
Build personal projects to demonstrate coding skills and experience
Prepare to answer common SWE interview questions, such as “Why do you want to work at this company?” and “What are your strengths and weaknesses?”

Mistakes to Avoid

BAD: Starting to practice LeetCode problems without a clear understanding of computer science fundamentals. GOOD: Building a strong foundation in computer science and programming before practicing LeetCode problems.

One common mistake that new grad SWEs make when preparing for interviews is starting to practice LeetCode problems without a clear understanding of computer science fundamentals. This can lead to frustration and difficulty in solving problems, as candidates may not have a solid grasp of the underlying concepts.

In contrast, building a strong foundation in computer science and programming before practicing LeetCode problems can significantly improve a candidate’s chances of passing the interview process. This includes developing a solid understanding of data structures, algorithms, and software design patterns, as well as practicing coding challenges and whiteboarding exercises.
