20 posts held, back to 3 February 2022 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 1 pageof Telegram’s post history, 20 posts per page.
Nothing published in the last 30 days. ERR and ER are rolling 30-day measures, so there is nothing to compute — we hold 20 posts for this entry, the most recent from 8 November 2022. An engagement rate over an empty window would be a number about nothing.
66 reactions across 11 posts, in 6 distinct kinds. The most used accounts for 57.6% of them.
| Reaction | Count | Share | Share, drawn |
|---|---|---|---|
| 👍 | 38 | 57.6% | |
| ❤ | 12 | 18.2% | |

No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.
Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.
Coverage. Reactions were read on 11 of the 20 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 66reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 20 most recent posts we hold, published 3 February 2022 to 8 November 2022, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

In case you weren’t aware, Tech Interview Handbook is using Docusaurus 2.0 to build its website. Both the handbook and Docusaurus 2.0 were built by the same person, me 🙂 Docusaurus is a project used by many open source projects to quickly build static websites, suitable for docs and blogs. I started contributing to Docusaurus in 2018 part-time and started Docusaurus 2.0 in the same year, and released a few alpha ver…

11. You might never feel ready for interviews and that's perfectly normal. Interviewing is a numbers game. Interview performance is a function of luck and preparation. The more you prepare, the "luckier" you get. You will fail some and you will pass some. You just need to pass one.

10. LeetCoding is a marathon, not a sprint. If you start too early, you run out of steam. Start too late and there's not enough time for spaced repetition to take effect. Recommend starting a few months in advance and spending 1hr a day doing a few questions per day. You should be in top shape when it's time for interviews. If you've completed all recommended practice questions, do the weekly contests. If you can sol…
9. You don't need to practice too many questions. 100-200 is sufficient for most. After a while, the questions are variations of previous questions and are based off the same patterns. The returns on practicing above 300 questions is marginal at best. The full list of 169 questions in Grind 75 (https://grind75.com) is 90% of what you need.

8. The chosen language doesn't matter as much as your mastery of the language. You don't have to pick up Python just because it's the best language for interviews. But if you have enough time (more than two months), it might be worth doing so.
7. Some topics are more important than the others. DFS, BFS, binary search, trees, graphs are the most important and common ones. If you're going for Google, practice DP. If you suck at DP like me, at least be good at backtracking with memoization.
6. You might not get to run your code during interviews. Interviewers aren't just evaluating how correct your code is, the signals you exhibit during the process matters as well. You can end up failing even though you wrote correct code but it's messy and not readable. You can also end up passing even if your code had a minor mistake but your code is super clean and well-structured. Getting an Accepted doesn't mean y…
5. If you find yourself stuck after half an hour on a question. Determine if you are close enough to cracking it. If you're close, try for a while longer. Otherwise read the solutions and move on. Learn the technique that was crucial to solving the question and internalize it. Revisit in a few day's time and try to solve it without referring to the answer this time. LeetCode also shows you similar questions for a pro…
Showing the 12 most recent of 20 posts we hold for @techinterviewhandbook. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.
A live page changes as we take new readings, so a citation should name the measurement it is based on, not just the URL. The line below cites the subscriber count as measured 24 August 2026 — this entry's latest reading, not the date you are reading this.
