Whether you’re in the market for a new coding job or just want to stay sharp in the one you have, it’s always important to do a skills check-up on the proficiencies you need for your job. Enter Daily Coding Problem, a mailing list service that sends you one coding problem per day (hence the name) to keep your analytical skills in top form.
One of the founders of the service, Lawrence Wu, stated that the email list service started “as a simple mailing list between me and my friends while we were prepping for coding interviews [because] just doing a couple problems every day was the best way to practice.”
Now the service offers this help for others who are practicing for interviews or for individuals needing to just stay fresh in what they do. The problems are written by individuals who are not just experts, but also who aced their interviews with giants like Amazon, Google, and Microsoft.
So how much would a service like this cost you? Free, but with further tiers of features for additional money. Like with all tech startups, the first level offers the basic features such as a single problem every day with some tricks and hints, as well as a public blog with additional support for interviewees. However, if you want the actual answer to the problem, and not just the announcement that you incorrectly answered it, you’ll need to pony up $15 per month.
The $15 level also comes with some neat features such as mock interview opportunities, no ads, and a 30 day money back guarantee. For those who may be on the job market longer, or who just want the practice for their current job, the $250 level offers unlimited mock interviews, as well as personal guidance by the founders of the company themselves.
Daily Coding Problem enters a field with some big players with a firm grasp on the market. Other services, like InterviewCake, LeetCode, and InterviewBit, offer similar opportunities to practice mock interview questions. InterviewCake offers the ability to sort questions by the company who typically asks them for that individual with their sights targeted on a specific company. InterviewBit offers referrals and mentorship opportunities, while LeetCode allows users to submit their own questions to the question pool.
If you’ve really got your eye on the prize of receiving that coveted job opportunity, Daily Coding Problem is a great way to add another tool in your tool box to ace that interview.
